Crypto

Wyn provides cryptographic primitives through the Crypto module. All functions return hex-encoded strings.

Methods

Method	Returns	Description
Crypto.sha256(s)	string	SHA-256 hash (hex)
Crypto.hmac_sha256(key, msg)	string	HMAC-SHA256 (hex)

Examples

// Hash a string
var hash = Crypto.sha256("hello")
println(hash)  // 2cf24dba5fb0a30e...

// HMAC for message authentication (e.g., JWT signing)
var sig = Crypto.hmac_sha256("secret-key", "message-to-sign")
println(sig)
