Module crypto 

Cryptographic operations for Seq

These functions are exported with C ABI for LLVM codegen to call.

API

# SHA-256 hashing
"hello" crypto.sha256                    # ( String -- String ) hex digest

# HMAC-SHA256 for webhook verification
"message" "secret" crypto.hmac-sha256    # ( String String -- String ) hex signature

# Timing-safe comparison
sig1 sig2 crypto.constant-time-eq        # ( String String -- Bool )

# Secure random bytes
32 crypto.random-bytes                   # ( Int -- String ) hex-encoded random bytes

# UUID v4
