httk.core.ed25519

Ed25519 signing with an optional accelerated backend.

All private keys accepted and returned by this module are standard 32-byte Ed25519 seeds. The stdlib implementation follows RFC 8032 and is kept as a portable fallback; cryptography is used automatically when installed.

Attributes

generate_ed25519_seed
derive_ed25519_public_key

Functions

ed25519_backend_available(→ bool)	Return whether backend can perform Ed25519 operations.
ed25519_generate_seed(→ bytes)	Generate a standard 32-byte Ed25519 private seed.
ed25519_public_key(→ bytes)	Derive the 32-byte public key for a 32-byte private seed.
ed25519_sign(→ bytes)	Return an RFC 8032 Ed25519 signature for message.
ed25519_verify(→ bool)	Return whether signature is valid, treating malformed input as false.
