string.encrypt()

Encrypts a string. Uses a symmetric key-based algorithm, in which the same key is used to encrypt and decrypt a string. The security of the encrypted string depends on maintaining the secrecy of the key. Uses an XOR-based algorithm that uses a pseudo-random 32-bit key, based on a seed passed by the user as a function parameter.

string.encrypt( string, key [, algorithm [, encoding [, IVorSalt [, iterations ] ] ] ] )

Returns: String

Argument Description
string
string, required

String to encrypt.

key
string, required

Key or seed used to encrypt the string. - 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.

algorithm
string, optional

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.

encoding
string, optional

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 .

IVorSalt
any, optional

Initialization Vector for algorithms with Feedback Mode that is not ECB, or Salt for Password Based Encryption algorithms

iterations
number, optional

number of Iterations for Password Based Encryption algorithms (ignored for all other algorithms). NIST recommends a minimum value of 1000.
