Module crypto 

Symmetric-crypto primitives for Python: HMAC, PBKDF2, AES-CBC, 3DES-CBC, PKCS#7 padding helpers, and the Fernet authenticated-encryption scheme.

All operations are delegated to synta-certificate’s backend traits so that no direct openssl::* imports are needed here.

Structs

PyFernet

Fernet symmetric authenticated encryption.

PyHmacDigest

Incremental HMAC computation.
