Module crypto 

Cryptographic operations for Seq

FFI entry points are grouped into per-primitive sub-modules and re-exported here so the flat public surface is unchanged.

API

• sha256, hmac-sha256, constant-time-eq — hash
• random-bytes, uuid4, random-int — random
• aes-gcm-encrypt, aes-gcm-decrypt — aes
• pbkdf2-sha256 — pbkdf
• ed25519-keypair, ed25519-sign, ed25519-verify — ed25519
