Lucee Function Reference
Choose a function:


Encrypts binary data using a specific algorithm and encoding method.


encryptbinary(any bytes,string key,[string algorithm,[any IVorSalt,[number iterations]]]):any


The arguments for this function are set. You can not use other arguments except the following ones.
Name Type Required Default Value Description
bytes any  Yes   Binary data to encrypt.  
key string  Yes   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  No cfmx_compat 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.  
  • IVorSalt any  No   Initialization Vector for algorithms with Feedback Mode that is not ECB, or Salt for Password Based Encryption algorithms  
    iterations number  No   number of Iterations for Password Based Encryption algorithms (ignored for all other algorithms). NIST recommends a minimum value of 1000.
