## Features

- **C14N** — XML Canonicalization (inclusive + exclusive, W3C compliant)
- **XMLDSig** — XML Digital Signatures (verify pipeline + template signing implemented; broader signing interop in progress)
- **XMLDSig** — XML Digital Signatures (verify pipeline + template signing with X.509 KeyInfo implemented; broader signing interop in progress)
- **XMLEnc** — XML Encryption (symmetric + asymmetric)
- **X.509** — Certificate-based key extraction and validation

- XMLDSig parsing, same-document URI dereference, transform chains, and digest verification
- XMLDSig full verify pipeline (`SignedInfo` canonicalization + `SignatureValue` verification)
- XMLDSig template signing pipeline (`DigestValue` fill + `SignedInfo` canonicalization + `SignatureValue` fill)
- XMLDSig signing KeyInfo writer for embedded X.509 certificates
- Built-in verification-key resolution from embedded X.509/DER/`KeyValue` sources and configured `KeyName`, X.509 subject, issuer/serial, SKI, or digest selectors
- RSA PKCS#1 v1.5 verification helpers for SHA-1 / SHA-256 / SHA-384 / SHA-512
- ECDSA verification helpers for P-256/SHA-256 and P-384/SHA-384
- RSA PKCS#1 v1.5 and ECDSA P-256/P-384 signing from PKCS#8 private keys
- Opt-in X.509 certificate-chain validation with explicit trust anchors, validity checks, CA constraints, and CRLs

Still in progress:
- XMLDSig signing KeyInfo writer, examples, and broader donor/CLI interop coverage
- XMLDSig signing examples and broader donor/CLI interop coverage
- XMLEnc encryption/decryption pipeline

Current toolchain target: latest stable Rust.
