`crypto` module

Cryptographic primitives backed by OpenSSL — hashes, HMAC, base64 (standard and URL-safe), hex, secure random, and constant-time comparison.

import "crypto" as crypto;

print(crypto.hash("sha256", "hello"));               // hex digest
print(crypto.hmac("sha256", "secret", "msg"));       // hex
print(crypto.b64_encode("Hello!"));                  // SGVsbG8h
var token = crypto.random_hex(16);                   // 32-char hex token

Hashing

Function	Description
`crypto.hash(algo, data)` → string	Hex digest. `algo`: `"sha256"`, `"sha512"`, `"sha1"`, `"md5"`.
`crypto.hmac(algo, key, data)` → string	Hex HMAC.

Codecs

Function	Description
`crypto.b64_encode(data)` / `b64_decode(s)`	Standard base64.
`crypto.b64url_encode(data)` / `b64url_decode(s)`	URL-safe base64 (no padding).
`crypto.hex_encode(data)` / `hex_decode(s)`	Bytes ↔ hex string.

Random

Function	Description
`crypto.random_bytes(n)` → string	`n` cryptographically secure random bytes.
`crypto.random_hex(n)` → string	`n` random bytes formatted as a `2n`-character hex string.

Comparison

Function	Description
`crypto.equals(a, b)` → bool	Constant-time string compare — use for tokens and HMAC verification.
