• 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:
For all algorithms except the default algorithm, ColdFusion MX 7 uses the Java Cryptography Extension (JCE) and installs a Sun Java 1.4.2 runtime that includes the Sun JCE default security provider. This provider includes the algorithms listed in the Parameters section. The JCE framework includes facilities for using other provider implementations.
