Class: Cryptography
Description
Decrypts an AES cipher text, ECB or CBC.
(string) = Cryptography.aesDecrypt(ciphertext,key,iv,paddingType)
Parameters
ciphertext: (string) AES encrypted message
key: (string) encryption key as a 16,24 or 32 byte string
iv: (string) a 16 byte IV to be used for CBC mode. If not provided ECB mode is used optional
paddingType: (number) type of padding to be used. Currently defined values are:
- 0: 0 padding optional
- 1: PKCS7 padding optional
Return values
Returns (string) deciphered message
