Crypto And Encoding Reference

Native path (alef run). Digests, HMAC, random bytes, and base64 helpers.

std.crypto

Function Role
sha256(data) SHA-256 hex digest of a string
hmac_sha256(key, data) HMAC-SHA256 hex digest
random_bytes(n) Cryptographic random bytes as hex (length n)
sha256_base64(data) SHA-256 over base64-decoded input (specialized form)

Additional primitives (AES, Ed25519, PBKDF2, and related helpers) ship on the

native binary; start with the functions above for signatures and tokens.

Runnable digests


import std.crypto { sha256, hmac_sha256, random_bytes }

fn main() {
    println(sha256("abc"))
    println(hmac_sha256("secret", "payload"))
    println(random_bytes(16))
}


alef run main.alef

std.encoding and std.base64

Function Role
std.encoding.base64_encode(s) Base64-encode a string
std.encoding.base64_decode(s) Base64-decode a string
std.base64.encode(s) / decode(s) Same helpers under the std.base64 namespace

Encode and decode


import std.encoding { base64_encode, base64_decode }

fn main() {
    let wire = base64_encode("hello")
    println(wire)
    println(base64_decode(wire))
}
