crypt_guard 3.0.1

CryptGuard is a post-quantum cryptography framework with NIST FIPS 203/204/205 (ML-KEM, ML-DSA, SLH-DSA) plus legacy Kyber/Falcon/Dilithium, combined with AES and XChaCha20.

// Content-axis typestate enforcement: `decrypt_msg` must NOT exist on a
// `Kyber<Decryption, _, Files, _>` instance in the default (non-legacy) build.
//
// `DecryptText::decrypt_msg` is implemented only for the `Message` content
// marker; the `Files` instance has `DecryptFile::decrypt_file` instead. With the
// legacy `KyberFunctions` trait gated out of the default build, calling
// `decrypt_msg` on a `Files` instance is a compile error.
