required

string

required

string

required

The Base64 IV returned by crypt.encrypt; at least 16 decoded bytes are required.

string

default:"\"CBC\""

The encryption mode; this implementation supports CBC only.

Returns

string

The decrypted plaintext bytes.

Invalid encodings, key/IV sizes, mode, or native decryption failures raise. Preserve the IV returned by encrypt.

local encrypted, iv = crypt.encrypt("hello", key)
local ok, plaintext = pcall(crypt.decrypt, encrypted, key, iv)
print(ok, plaintext)
