Category

binary

Arguments

The arguments for this function are set. You can not use other arguments except the following ones.
Name Type Required Default Value Description
binaryData any  Yes   Binary data to decrypt.  
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  
    • 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.  
    precise boolean  No false if set to true the input must follow the rule for that encoding a 100%, the decryptor will not try to interpret inputs that are not a 100% correct. This should be used to avoid false positives.
