Lucee Function Reference
Function ENCRYPTBINARY
Encrypts binary data using a specific algorithm and encoding method.
Example
encryptbinary(any bytes,string key,[string algorithm,[any IVorSalt,[number iterations]]]):any
Arguments
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. 

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. 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.
