Detailed Methods

crypto.uuid()

Generates a cryptographically strong UUID version 4:

var id = crypto.uuid();
print("Session ID: " + id);

---

crypto.sha256(input)

Calculates standard 256-bit SHA-2 digest:

var hash = crypto.sha256("password123");
print("Hash: " + hash);

---

crypto.hmac_sha256(message, secret_key)

Produces an HMAC authentication signature using SHA-256:

var payload = "GET /api/v1/orders";
var secret = "my_super_secret_key";

var signature = crypto.hmac_sha256(payload, secret);
print("API Signature: " + signature);

---

crypto.base64_encode(text) & crypto.base64_decode(encoded)

Fast binary-to-text Base64 conversions:

var raw = "Hello, RayQuiro!";
var encoded = crypto.base64_encode(raw);
print("Base64: " + encoded);

var decoded = crypto.base64_decode(encoded);
print("Restored: " + decoded);

---

crypto.random_bytes(count)

Generates random cryptographically secure hex strings:

var token = crypto.random_bytes(16);
print("Csrf Token: " + token);
