encryptBinary Argument Reference

binaryData any
Required

Binary data 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
Default: CFMX_COMPAT

The algorithm to use to encrypt the string.
ColdFusion Standard Edition installs the following algorithms:
* CFMX_COMPAT: the algorithm used in ColdFusion MX and prior releases. This algorithm is the least secure option (default).
* 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.

NOTE: ColdFusion Enterprise Edition installs RSA BSafe Crypto-J library, which provides FIPS-140 Compliant Strong Cryptography. This also includes:
* DESX: The extended Data Encryption Standard symmetric encryption algorithm.
* RC2: The RC2 block symmetric encryption algorithm defined by RFC 2268.
* RC4: The RC4 symmetric encryption algorithm.
* RC5: The RC5 encryption algorithm.
* PBE: Password-based encryption algorithm defined in PKCS #5.
* AES/GCM/NoPadding: Encryption algorithm.
NOTE: If you install additional cryptography algorithms, you can also specify any of its encryption and decryption algorithms.
Values:
  • CFMX_COMPAT
  • AES
  • BLOWFISH
  • DES
  • DESEDE
  • DESX
  • RC2
  • RC4
  • RC5
  • PBE
  • AES/GCM/NoPadding

iv binary

THIS PARAMETER IS MUTUALLY EXCLUSIVE WITH SALT.

Specify this parameter to adjust ColdFusion encryption to match the details of other encryption software.
* For Block Encryption Algorithms: This is the binary Initialization Vector value to use with the algorithm. The algorithm must contain a Feedback Mode other than ECB. This must be a binary value that is exactly the same size as the algorithm block size.
NOTE: If you specify this parameter, you must also specify the algorithm parameter.

salt binary

THIS PARAMETER IS MUTUALLY EXCLUSIVE WITH IV.

Specify this parameter to adjust ColdFusion encryption to match the details of other encryption software.
* For Password Based Encryption Algorithms: This is the binary Salt value to transform the password into a key.
NOTE: If you specify this parameter, you must also specify the algorithm parameter.

iterations numeric
Default: 0

The number of iterations to transform the password into a binary key. Specify this parameter to adjust ColdFusion encryption to match the details of other encryption software.

NOTE: If you specify this parameter, you must also specify the algorithm parameter with a Password Based Encryption (PBE) algorithm.
NOTE: This parameter is used with the salt parameter. Do not specify this parameter for Block Encryption Algorithms.
NOTE: You must use the same value to encrypt and decrypt the data.
