Encoding, hashing, encryption, and compression.
Available functions
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.
