feat(xmlsec1): add keys, KeyInfo, templates and signature transforms on the owned tree - #455
The libxmlsec1 keys, KeyInfo, keys managers, templates, xmltree helpers and the digest, HMAC and signature transforms run over the owned document tree through its handles; no C library is used.
Core: key values, incremental digests and HMAC, private key import into a key inventory; the owned tree keeps an unlinked run of siblings (unlink_children), parses a fragment in the namespace context of an element or the document node under the policy (parse_in_context) and copies a subtree from another tree with its ID registrations (copy_from). The serializer writes a carriage return in text as 
 and namespace declarations before attributes, as libxml2 does.
Tree layer: xsFreeNodeList, xsParseInNodeContext, xsDocCopyNode, document::subtree; the library policy is published there as verification and signing snapshots, which a policy setter replaces as a complete pair, and every libxmlsec1 run uses the snapshot it started under.
xmltree.h, templates.h, keys.h, keysdata.h (binary value, symmetric and RSA/DSA/EC/DEREncodedKeyValue klasses), keyinfo.h (KeyName, KeyValue, RetrievalMethod, KeyInfoReference, bounded by the policy's URI classes and depth for key retrieval), keysmngr.h (manager, store protocol, simple store), digest/HMAC/signature klasses in the built-in crypto table, xmlSecCryptoAppKeyLoadMemory. MD5 and RIPEMD-160 klasses come with the legacy-algorithms feature.
Functions that read or write a file themselves are not offered: xmlSecKeyReadBinaryFile, xmlSecSimpleKeysStoreLoad, xmlSecSimpleKeysStoreLoad_ex, xmlSecSimpleKeysStoreSave; the headers say so and point to the memory entry points. The built-in table loads keys from memory only. Templates are built in the document they belong to.
Testing
Every C program under crates/xml-sec-xmlsec1/tests/c prints the same as libxmlsec1 1.3.13 (capi --xmlsec1); tests (with the xmlsec1 oracle and SoftHSM), clippy with all features, formatting, the header check and the clean C API check pass locally on macOS; CI runs the full matrix.
… import
The core pieces the libxmlsec1 key and transform surface builds on:
- parse_key_value_child reads one KeyValue child, and KeyValueInfo
converts to and from SubjectPublicKeyInfo DER
- IncrementalDigest and IncrementalHmac hash data fed in pieces through
the selected provider; HmacPolicy::validate_output checks an output
length
- verify_signature_value checks a SignatureValue under a policy
- KeyInventory derives the public key of a private key and imports
private keys from OpenSSL containers (traditional PEM included, with
SEC1, PKCS#1 and DSA normalization); the command line uses it instead
of its own import
Part of #451
- xmltree.h content, editing and QName helpers (xmlSecAddChild and
siblings, xmlSecEnsureEmptyChild, xmlSecReplace{Node,Content,NodeBuffer}
and their AndReturn forms, xmlSecAddIDs, xmlSecCreateTree, hex and size
content, escaping, xmlSecGetQName, the QName integer and bit-mask
tables) work through the tree handles, without libxml2.
- The owned tree keeps an unlinked run of siblings, as libxml2 hands
back replaced content or a parsed fragment: unlink_children and
parse_in_context, which parses content in the namespace bindings in
scope at an element under the operation policy.
- The tree layer adds xsFreeNodeList and xsParseInNodeContext; a refused
fragment becomes the thread's last tree error.
- A carriage return in text serializes as 
, as xmlDocDumpMemory
writes it.
- tests/c/xmltree.c prints the same trees, results and reports as
libxmlsec1 1.3.13.
Part of #451
- Signature, Reference, Object, Manifest, EncryptedData, EncryptedKey,
KeyInfo, X509Data and transform-content templates build in the
caller's document through the tree handles, as libxmlsec1 builds them.
- An XSLT stylesheet template is parsed as its own document and its
element copied into the transform, as libxml2 moves it.
- The owned tree copies a subtree from another tree (copy_from), the
copy declaring the bindings it inherited; the tree layer exports it as
xsDocCopyNode, staging the copy so no two documents are locked at once.
- The serializer writes an element's namespace declarations before its
attributes, as libxml2 does.
- tests/c/templates.c prints the same trees, results and reports as
libxmlsec1 1.3.13.
Part of #451
…wned tree
- keys.h: keys, key requirements and use-with records; keys read from
memory through a klass's binary reader.
- keysdata.h: the binary key-data value and its klass methods; the
symmetric klasses (AES, Camellia, ChaCha20, DES, HMAC, ConcatKDF,
PBKDF2, HKDF) and the RSA, DSA, EC and DEREncodedKeyValue klasses in
the built-in crypto table. An asymmetric KeyValue is read by the core's
key-value reader over the element's own subtree, copied out of the
tree (document::subtree).
- keyinfo.h: the KeyInfo context, reading and writing a KeyInfo element
through its children's klasses, KeyName, KeyValue, RetrievalMethod and
KeyInfoReference.
- keysmngr.h: keys managers, the key store protocol and the simple keys
store with lax search.
- The functions that read or write a file themselves are not offered:
xmlSecKeyReadBinaryFile, xmlSecSimpleKeysStoreLoad, its _ex form and
xmlSecSimpleKeysStoreSave; the headers say so and point to the memory
entry points.
- xmlSecTransformCtxDebugXmlDump prints an unset URI as NULL, as
libxmlsec1 does.
- tests/c/keys.c, symkeys.c, asymkeys.c and keyinfo.c print the same as
libxmlsec1 1.3.13.
Part of #451
- The built-in crypto table carries the SHA-1, SHA-2 and SHA-3 digest
klasses, the HMAC klasses and the RSA, RSA-PSS, DSA and ECDSA signature
klasses over the core's incremental digests, HMAC and signature
verification and signing; MD5 and RIPEMD-160 come with the
legacy-algorithms feature, as libxmlsec1 builds them on request.
- xmlSecCryptoAppKeyLoadMemory reads private keys in every container the
core's importers accept and public keys in PEM or DER, asking a
password only of a protected container. The table loads no file.
- The library policy has one owner, the tree layer: it publishes
verification and signing snapshots and republishes complete
replacements, which xmlSecTransformHmacSetMinOutputBitsSize uses; a
run keeps the snapshot it took.
- capi --xmlsec1 builds the library with the oracle's MD5 and RIPEMD-160
klasses and runs the programs from the repository root; digests.c,
hmac.c, signatures.c and app.c print the same as libxmlsec1 1.3.13.
Part of #451
This pull request adds owned-tree operations, shared signing and verification policies, and OpenSSL-compatible key import. It implements XMLsec-compatible C APIs for keys, KeyInfo, XML trees, templates, and digest, HMAC, and signature transforms. C programs exercise the APIs.
Changes: XML tree and XMLDSig foundations
Layer / File(s)
Summary
Owned-tree operations and XML node APIs src/document/owned_tree.rs, crates/xml-sec-libxml2/src/{document.rs,nodes.rs,ffi/tree.rs}, src/parser_xmloxide/serial/xml.rs
Owned trees support detached sibling runs, context parsing, and subtree copying. The libxml2 C layer adds node-list freeing, copying, and context parsing. Serialization orders namespace declarations first and emits carriage returns as 
.
Policy snapshots and XMLDSig primitives crates/xml-sec-libxml2/src/policy.rs, src/policy.rs, src/xmldsig/*
Signing and verification policies use paired Arc snapshots that can be republished. XMLDSig adds incremental digest and HMAC APIs, SPKI conversion, public KeyValue child parsing, and signature-value verification.
OpenSSL key import and CLI integration src/key_manager*, tools/xmlsec1/src/{key_material.rs,commands.rs}, tools/xmlsec1/Cargo.toml
The key inventory imports PKCS#8 and traditional RSA, EC, and DSA keys, including supported encrypted PEM containers. CLI key decoding uses the shared importer and passes resource policies.
XMLsec-compatible C API
Layer / File(s)
Summary
Key objects and key-data classes crates/xml-sec-xmlsec1/src/ffi/{keys.rs,keysdata.rs,app.rs,asymkeys.rs,symkeys.rs,keysmngr.rs}
The FFI adds key and key-requirement operations, binary and symmetric key data, RSA/DSA/EC key data, in-memory key loading, and key-manager and store operations.
KeyInfo and references crates/xml-sec-xmlsec1/src/ffi/keyinfo*
KeyInfo contexts read and write key names and values, resolve retrieval methods and KeyInfo references, and use manager and store lookups.
XML-tree helpers and templates crates/xml-sec-xmlsec1/src/ffi/xmltree/*, crates/xml-sec-xmlsec1/src/ffi/templates.rs
The FFI adds XML content, editing, and QName operations. Template APIs construct signature, encryption, KeyInfo, X.509, reference, and transform nodes.
Digest, HMAC, and signature transforms crates/xml-sec-xmlsec1/src/ffi/transforms*, crates/xml-sec-xmlsec1/src/ffi/crypto.rs
The built-in table registers digest, HMAC, and signature transforms. They process input incrementally and apply signing or verification policy. Legacy algorithms are feature-gated.
C API validation and build integration crates/xml-sec-xmlsec1/tests/c/*, tools/xml-sec-tools/src/{capi.rs,hardening.rs,xmlsec1_headers.rs}, crates/xml-sec-xmlsec1/include/xmlsec/*
C programs exercise the APIs. The C API build and hardening runner include the programs. The headers and unavailable-function list document file-based key operations that are not offered.

Explanation
The title names the main change: adding keys, KeyInfo, templates, and signature transforms to the xmlsec1 crate on the owned tree. The raw summary and PR objectives confirm these are the primary additions (key values, KeyInfo traversal, templates, digest/HMAC/signature transforms, and tree helpers). The title omits key managers, tree helpers, and policy snapshots, which is acceptable because it need not cover every detail. The title is 86 characters, slightly long but within a readable single-sentence form.

Do not apply the verification minimum to signing parameters.
If verification requires 256 output bits but signing permits 128, reading a 128-bit HMAC-SHA256 method fails here before signing can proceed. The length is valid under the signing policy. Defer operation-specific validation to set_key, which already selects the correct policy. (raw.githubusercontent.com)

Charge the supplied key before validating it.
With rustcrypto enabled and max_key_candidates = 0, a valid HMAC can still return Ok(true). The budget constructor starts at zero, and this function never charges the root key. Document verification explicitly charges that inspection. Call charge() before key.validate_policy() so the standalone entry point enforces the same limit. (raw.githubusercontent.com)

Pass the operation certificate session to native verification.
For AwsLcFipsProvider, this call reaches verify(), which creates a standalone certificate session. Native SPKI processing therefore does not consume the policy-scoped account created above. A budget that admits key validation but cannot admit the additional native decode does not stop that decode.

Include retained inventory material in the early reservation.
When the inventory is near max_external_resource_total_bytes, check_new_name() checks only the additional name. decode_pem() then checks the source and decoded buffer against the full limit, without the existing inventory or name. It can allocate and decrypt beyond the aggregate limit before add_private_der_inner() rejects the import. Pass the remaining allowance through decoding and normalization, or preflight the complete live total before allocation. (raw.githubusercontent.com)

Check the encoded IV length before allocating it.
A DEK-Info value with a very long hexadecimal IV makes decode_hex() allocate half that length. The filter rejects the result only afterward. This allocation occurs before the aggregate reservation, although the valid IV is only 8 or 16 bytes.
Require encoded_iv.len() == 2 * cipher.iv_len() before decoding. This also preserves early rejection of malformed protection metadata.

Limit RSA candidate normalization to the remaining aggregate budget.
decrypt_with_private_keys keeps one certificate_budget across all selected recipient keys. Each key's source bytes stay charged to that budget. The RSA normalization path in load_recipient_private_key passes the full resources policy to decode_rsa_private_with_inventory. The temporary normalization check therefore uses the full aggregate limit and ignores the bytes already charged for earlier keys. With two keys, the second normalization can pass its local check and still push the operation past max_external_resource_total_bytes.
import_explicit_private_key already reduces the normalization limit by the charged total. Apply the same limit in the RSA decrypt path.

Passing a null doc makes the template constructors fail. libxmlsec1 accepts a null doc.
libxmlsec1 documents doc as "the pointer to signature document or NULL". With NULL, the caller attaches the tree later with xmlSetTreeDoc. Here xsNewDocNode(doc, ...) returns null when document_of(doc) is None (crates/xml-sec-libxml2/src/ffi/tree.rs:446-481). The call xmlSecTmplSignatureCreate(NULL, ...) therefore reports "xmlNewDocNode" and returns NULL. xmlSecTmplEncDataCreate at lines 874-888 has the same failure. The owned tree may not be able to support nodes without a document. If so, document this limitation in the C headers, as the PR does for the file-based APIs. Then callers get an explicit message and not a generic libxml failure.

snapshot write lock, and keep the current policy pair intact until both edits
succeed. Serialize the final replacement commit so concurrent edits cannot
overwrite one another; ensure a closure panic leaves the published pair and
snapshot lock usable.
Review comments at @crates/xml-sec-xmlsec1/src/ffi/keyinfo.rs:
- Line 954: Update the enabled-list check in the key-info export path to test
the actual key-value class ID from (*value).id rather than the KeyValue wrapper
ID in id. Preserve the existing enabled-list behavior while ensuring disabled
symmetric key material cannot pass the check.
Review comments at @crates/xml-sec-xmlsec1/src/ffi/keyinfo/references.rs:
- Line 303: Update the RetrievalMethod resolution path at the early return so an
absent Type does not skip retrieval unless strict unknown-type checking rejects
the reference. For resolvable resources, retrieve the XML and infer its klass
from the root; perform type-mismatch checks only when an expected type is
present.
Review comments at @crates/xml-sec-xmlsec1/src/ffi/keys.rs:
- Around line 1064-1067: Update the xmlSecKeySetValue flow so that when
owned.value equals value, it returns success before calling
xmlSecKeyDataDestroy; preserve the existing destruction and assignment behavior
when the pointers differ.
- Line 827: Update xmlSecKeyCopy to check whether the source and destination
pointers are equal before calling xmlSecKeyEmpty; return 0 for a self-copy so
the source key remains unchanged.
- Around line 1236-1238: Update xmlSecKeyAdoptData to check whether the exact
data pointer is already owned before calling xmlSecPtrListSet or
xmlSecPtrListAdd; if so, leave the list unchanged. Preserve the existing
replacement behavior for different pointers with a matching ID and the add
behavior for unmatched IDs.
- Line 224: Update xmlSecKeyUseWithCopy to return 0 when dst and src refer to
the same record, before calling xmlSecKeyUseWithSet. Preserve the existing copy
path for distinct records.
Review comments at @crates/xml-sec-xmlsec1/src/ffi/transforms/digests.rs:

the algorithm is permitted by the published digest policy for object.operation
before creating the incremental state. Preserve provider capability checks, and
ensure a policy-excluded algorithm cannot proceed to verification success.
Review comments at @crates/xml-sec-xmlsec1/src/ffi/transforms/hmac.rs:
- Line 397: In the HMAC key-admission flow around policy::verification_at, check
the cached policy’s current validity before the remaining authorization checks
can admit the key. Use the established policy-validation mechanism and reject
expired authorization, preserving the existing checks for valid policies.
Review comments at @crates/xml-sec-xmlsec1/src/ffi/transforms/signatures.rs:
- Around line 418-420: The signature flow re-reads policy during collection and
final processing, so a concurrent policy change can alter limits mid-run. Update
the signature operation around `signing_at` and `verification_at` to capture one
policy snapshot at the start and pass it through every collection step and final
signing or verification, preserving that snapshot for the entire run.
Review comments at @src/document/owned_tree.rs:
- Line 666: Update the copy_from flow around register_imported_ids to preserve
applicable explicitly registered ID attributes, not only xml:id, so
element_by_id can find copied nodes after they are linked. Apply the same
preservation during FFI copy staging, reusing the existing registration
mechanisms and ensuring registrations remain associated with the copied
attributes.
Review comments at @src/key_manager/openssl.rs:
- Line 531: Update normalize_dsa before BoxedMontyForm::new to convert g to the
precision of components.p() using the existing fallible conversion mechanism,
returning UNSUPPORTED if g cannot fit. Pass the widened value to
BoxedMontyForm::new so its precision matches p.

Review comments at @src/key_manager/openssl.rs:
- Line 527: Keep the DSA exponent protected from the moment it is parsed by

validation or public-value comparison. Preserve that protection through those
early-return paths and when constructing the signing key, avoiding an
unprotected temporary copy.
- Line 174: Update the import flow around decode_pem so its allocation and
decryption checks account for the retained inventory and the additional name,
not just the full configured limit; pass the remaining allowance through
decoding and normalization or preflight the complete live total before
allocation. Preserve enforcement of the aggregate byte limit before decoding can
exceed it.
- Around line 319-320: Check that encoded_iv has exactly twice cipher.iv_len()

Review comments at @src/xmldsig/verify/signature_value.rs:

- Key retrieval: RetrievalMethod and KeyInfoReference dereference only
the URI classes the library policy admits for key retrieval, and
KeyInfoReference depth is bounded by the policy.
- KeyName: XMLSEC_KEYINFO_FLAGS_KEYNAME_STOP_ON_UNKNOWN stops the read on
a name the keys manager does not know.
- DEREncodedKeyValue does not replace a key already found; a KeyValue of
a klass the enabled list leaves out is not written.
- Keys: copying a use-with record, requirements or a key onto itself and
setting or adopting data the key already owns keep their state.
- Digest transforms admit the method only under the operation's policy,
checked for its authorized lifetime first.
- HMAC: the output length is read under the policy of the operation, and
the key is admitted only under a policy in force.
- Signature transforms keep the policy snapshot a run started under for
the bound on the collected bytes and the final sign or verify.
- xmlSecReplaceContentAndReturn takes the new node out before freeing the
old content and fails when it cannot be linked;
xmlSecReplaceNodeBufferAndReturn replaces the document element and
takes the edit back when a parsed node cannot be linked.
- Parsing in context accepts the document node, which binds no prefix; a
context that is neither reports the bad-context code.
- Library policy: republishing runs the edits on copies outside the
snapshot lock, one caller at a time, so an edit may read the policy, a
panicking edit leaves it published, and concurrent edits are kept.
- OwnedTree::copy_from carries the IDs a caller registered on the copied
attributes.
- OpenSSL DSA import: the generator is resized to the modulus precision
before the g^x check, refusing one that does not fit, and the private
exponent is wiped on every path; a DEK-Info IV of the wrong length is
refused before decoding; early reservations count the inventory's
retained material and the new name.
- Standalone signature-value verification charges the supplied key as an
inspected candidate and, as document verification now does too, passes
the operation's certificate session to the provider.
- xmlsec1 CLI: RSA recipient normalization uses only the aggregate budget
the operation has left.
- Decoded symmetric key text is wiped before it is freed; an unsupported
key format reports XMLSEC_ERRORS_R_INVALID_FORMAT (17); templates
report a NULL document explicitly, and xs_tree.h documents that a node
is created in a document.
- C programs: app.c fails when a key fixture does not load, xmltree.c
prints conversion results after the call, signatures.c adds a
DSA-SHA256 vector; xmloxide patch regenerated; tree.h maps
xsNodeSetContent with an int result for every libxml2 version.
Each correctness fix carries a regression test that fails without it.

Pass the remaining aggregate allowance to the direct signing decoder.
The direct RustCrypto path calls decode_signing_key(..., resources) after charging the key bytes. For a traditional key, that decoder can call KeyInventory::add_openssl_private_key with the full aggregate limit. If an earlier candidate consumed part of the budget, normalization can therefore pass its resource check when the cumulative source bytes and new allocation exceed the operation limit. Pass remaining_workspace(resources, material_budget, key_bytes.len()) to this path, as the other explicit import paths do. (raw.githubusercontent.com)
Based on learnings, “Public-path tests must demonstrate that the compiled policy reaches every affected enforcement point.”

crates/xml-sec-xmlsec1/src/ffi/keysdata.rs:1280 Major · Security & Privacy · Heavy lift
Enforce key_sources on the C API KeyValue path.
The C API reads KeyValue children from a document KeyInfo without checking VerificationPolicy.key_sources. xmlSecKeyInfoNodeRead and value_xml_read select the klass only through child_klass, which checks the enabled class list. The Rust resolver rejects a disallowed KeyValue, but the C path does not call it. The C verification transform then accepts the key with no source information. An embedded public key can therefore verify a signature even when key_sources excludes KeyValue.
Check the typed key_sources permission before a document key source is accepted in the C read path. Apply the same check to the other XML key sources the C path reads: KeyName, X509Data, DEREncodedKeyValue, and KeyInfoReference. Add a public C API test that denies KeyValue and asserts that verification fails.

Preserve private-key errors when public-key fallback is not applicable.
For a protected private PEM with a missing or wrong password, private_key returns ProtectedContainer. The unconditional or_else replaces that error with the public-key import error, so the caller loses the password failure needed to recover. Retry public import only when the private importer identifies a non-private container; preserve protected-container and policy errors. (raw.githubusercontent.com) Based on learnings, Rust error handling must not silently suppress actionable failure kinds.

existing failure return behavior.
- Line 554: Update the replacement path in xmlSecReplaceNodeBufferAndReturn to
use an OwnedTree operation instead of separate sibling-link, unlink, and free

the built replacement nodes with the old node passed as released, so its ID
claims can transfer and registration failures roll back the edit.
