Lucee Function Reference
Function DECRYPT
Decrypts a string that is encrypted with the Encrypt function.
Example
decrypt(string encrypted_string,string key,[string algorithm,[string encoding,[any IVorSalt,[number iterations]]]]):string
Arguments
The arguments for this function are set. You can not use other arguments except the following ones.
Name  Type  Required  Default Value  Description 

encrypted_string  string  Yes  String to decrypt.  
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. 
encoding  string  No  uu 
The binary encoding used to represent the data as a string. Must be the same as the algorithm used to encrypt the string. 
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.
