pybergshamra documentation

pybergshamra is a Python binding for the Bergshamra XML Security library – a pure-Rust implementation of XML Digital Signatures (XML-DSig), XML Encryption (XML-Enc), C14N canonicalization, and cryptographic primitives.

Features

  • XML Digital Signatures – sign and verify (RSA, EC, Ed25519, HMAC, post-quantum)

  • XML Encryption – encrypt and decrypt (AES-CBC/GCM, RSA-OAEP key transport)

  • C14N canonicalization – inclusive, exclusive, with/without comments

  • Key management – RSA, EC, Ed25519, X25519, HMAC, AES, 3DES, PKCS#12, X.509

  • Certificate validation – X.509 chain building and verification with CRL support

  • Cryptographic primitives – digest, PBKDF2, HKDF, ConcatKDF

  • Post-quantum signatures – ML-DSA-44/65/87, SLH-DSA

  • Anti-XSW protection – strict verification mode

  • Zero Python dependencies – ships as a single native extension
