For the CFMX_COMPAT algorithm, any combination of any number of characters; used as a seed used to generate a 32-bit encryption key.
For all other algorithms, a key in the format used by the algorithm. For these algorithms, use the GenerateSecretKey function to generate the key.
The algorithm to use to decrypt the string. Must be the same as the algorithm used to encrypt the string.
CFMX_COMPAT(default): the CFML specific algorithm. This algorithm is the least secure option
AES: the Advanced Encryption Standard specified by the National Institute of Standards and Technology (NIST) FIPS-197
BLOWFISH: the Blowfish algorithm defined by Bruce Schneier
DES: the Data Encryption Standard algorithm defined by NIST FIPS-46-3
DESEDE: the "Triple DES" algorithm defined by NIST FIPS-46-3 You may also specify other algorithm names as well as the feedback mode and padding scheme where applicable (in the format algorithm/mode/padding) as documented in the Java Cryptography Architecture (JCA) Reference Guide.
The binary encoding used to represent the data as a string. Must be the same as the algorithm used to encrypt the string.
Base64: the Base64 algorithm, as specified by IETF RFC 2045
Hex: the characters A-F and 0-9 represent the hexadecimal byte values
UU(default): the UNIX standard UUEncode algorithm
Initialization Vector for algorithms with Feedback Mode that is not ECB, or Salt for Password Based Encryption algorithms
Alias: IV, Salt
number of Iterations for Password Based Encryption algorithms (ignored for all other algorithms). NIST recommends a minimum value of 1000.
if set to true the input must follow the rule for that encoding a 100%, the decryptor will not try to interpret inputs that are not a 100% correct. This should be used to avoud false positives.
