Specifies the message digest algorithm to use to protect the passwords that are stored in the database when using built-in authentication. The value is the name of a message digest algorithm available from one of the Java Cryptography Extension (JCE) providers registered in the JVM. Some examples of valid values are MD5, SHA-256, and SHA-512.
The specified algorithm will be applied on the concatenation of the user name and the password before it is stored in the database.
If the value of algorithm is NULL or an empty string, SHA-1 will be used on the password only.
For a newly created database, the default value is SHA-256, if that algorithm is available. If SHA-256 is not available, the default is SHA-1.
