Functions

Function	Input	Output
list_hash_algo()	—	{ "sha256", …, "sdbm" }
list_encode_algo()	—	{ "hex", "base64" }
is_hash(name)	string	boolean
is_encoding_algo(name)	string	boolean
hash_string(data, algorithm)	string, string	hex digest
hash_file(path, [algorithm])	path, string?	hex digest (default sha256)
encode(data)	string	hex
encode(data, encoding)	string, "hex"|"base64"	encoded string
encode(data, key, hash)	string, string, string	HMAC hex

Hash algorithms

• Digests: sha256, sha512, sha1, md5
• Fingerprints: fnv1a64, fnv1a32, crc32, djb2, sdbm

Examples

local sha = beez.crypto.hash_string("payload", "sha256")
local file_hash = beez.crypto.hash_file("dist/app.tar.gz")
local b64 = beez.crypto.encode("hello", "base64")
local mac = beez.crypto.encode("message", "secret-key", "sha256")

Use with beez.net.download_and_verify to verify downloads.
