In `@compatibility/libxmlsec1-1.3.13-rules.json`:
- Around line 125-130: Update the name_regex in the native-cli-options rule to
match the implemented --aeskey spelling instead of --aes-key, and add --node-id
to the accepted option alternatives; leave the other option spellings unchanged.
In `@compatibility/libxmlsec1-1.3.13.json`:
- Around line 23-26: Align the native-cli-tests evidence with what
capability_ledger::native_cli_claims_match_process_and_upstream_runner_tests
actually validates: either expand the guard to cover process_contract.rs,
upstream_runner.rs, and all claimed native classifications, or narrow the
description and classifications to the existing seven commands, four options,
and two exit statuses.
In `@tests/capability_ledger.rs`:
- Around line 770-808: Extend
native_cli_claims_match_process_and_upstream_runner_tests to include the
unknown-command CLI exit status, asserting its outcome is planned-cli-surface.
Also validate the claimed exit codes for success, failure, and unknown-command,
using the ledger entries’ recorded exit-code values.
In `@tools/xmlsec1/src/args.rs`:
- Around line 122-133: Update the Arity::Value branch in option_arity parsing to
consume the next remaining argument verbatim, removing the starts_with("-")
filter while retaining MissingOptionValue when no next argument exists.
In `@tools/xmlsec1/src/capabilities.rs`:
- Around line 54-59: Update contains_all so it returns false when requested
contains no capability names, including cases that produce no values after
splitting; preserve the existing all-capabilities validation for non-empty
requests.
In `@tools/xmlsec1/src/commands.rs`:
- Around line 481-534: Update the file-writing branch in keys to create the
key-store file with Unix permissions 0o600 before writing the generated AES key
material, rather than relying on fs::write’s default permissions. Preserve the
existing path-specific CommandError::Io mapping and stdout behavior.
- Around line 227-244: Update verification_policy so the legacy RsaSha1,
DsaSha1, and HmacSha1 algorithms are added to
allowed_legacy_signature_algorithms only when the explicit compatibility flag is
enabled; otherwise preserve VerificationPolicy’s default rejection behavior.
In `@tools/xmlsec1/src/key_material.rs`:
- Around line 111-118: Update parse_pem to accept the PEM file path separately
from expected_label, and use that path when constructing InvalidPem for parse,
trailing-content, or label-validation failures. Update every parse_pem call site
to pass the corresponding file path while retaining expected_label for PEM label
validation.
- Around line 59-82: Update tools/xmlsec1/src/key_material.rs lines 59-82 in
load_signing_key to add RSA PKCS#1 PEM and DER fallbacks alongside the existing
PKCS#8 handling. Update tools/xmlsec1/src/key_material.rs lines 84-100 in
load_verification_key to accept the PKCS#1 RSA PUBLIC KEY PEM label and validate
DER input before assigning it to public_key_bytes.

Preserve attributes on matching KeyInfo placeholders
placeholder.range() includes the placeholder attributes, so replacement removes attributes such as Id. Preserve these attributes or reject attribute-bearing placeholders, and add a regression test.

When an RSA encryption template already contains recipient key material such as EncryptedKey/KeyInfo/X509Data or RSAKeyValue, and --pubkey-pem or --pubkey-cert-* supplies a different public key, this merge replaces only the wrapped-key CipherValue while preserving the template's old recipient metadata. The command therefore succeeds with ciphertext wrapped for the supplied key but an output document identifying another key, so a recipient following the emitted KeyInfo cannot decrypt it; validate that existing key material matches the selected key or replace it alongside the cipher value.

When a signing template contains a <Reference> targeting the direct KeyInfo (for example URI="#key-info" on a KeyInfo Id="key-info" placeholder), the digest and signature are computed before this writer inserts the certificate data. The returned document therefore contains a reference digest over the old placeholder and fails verification as soon as the populated KeyInfo is dereferenced; apply the writer before the digest pass or recompute the affected digests after mutation.

When the core signature is valid but a processed <Manifest> reference fails, verify() later returns a nonzero status because it checks manifest_references, while --print-xml-debug derives the root context status only from result.status and emits status="OK". Automation consuming the diagnostic XML can therefore treat the same verification as successful despite the process rejecting it; derive the root status and failure reason from the aggregate signature and manifest result.
