Cryptography

Encoding, hashing, encryption, and compression.

Function navigation	Description
`base64_decode`	Decodes Base64 input with Base64 decoder and returns the decoded bytes as a Lua string.
`base64_encode`	Encodes a Lua string’s bytes with Base64 encoder, using = padding and no line breaks.
`crypt.decrypt`	Decrypts Base64 ciphertext with a Base64-decoded key and required Base64 IV using AES CBC or ECB.
`crypt.encrypt`	Encrypts Lua string bytes with AES CBC, ECB, or CTR using a Base64-decoded key, then returns Base64 ciphertext and the IV result.
`crypt.generatebytes`	Generates random bytes with random byte generator and returns them Base64-encoded as a Lua string.
`crypt.generatekey`	Generates 32 random raw bytes with random byte generator and returns them Base64-encoded as a Lua string.
`crypt.hash`	Hashes Lua string bytes with a supported crypto library hash algorithm and returns a lowercase hexadecimal digest.
`crypt.hmac`	Computes a crypto library HMAC over Lua string bytes using a raw Lua string key and returns a Base64 digest.
`crypt.random`	Generates raw random bytes with random byte generator and returns them as a Lua string.
`lz4compress`	Compresses Lua string bytes with LZ4 block compression and returns the raw compressed bytes as a Lua string.
`lz4decompress`	Decompresses raw LZ4 block bytes with LZ4 block decompression and returns raw decompressed bytes as a Lua string.
