derby.authentication.builtin.algorithm

Function

Specifies the message digest algorithm to use to protect the passwords that are stored in the database when using NATIVE or BUILTIN 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.

Syntax

derby.authentication.builtin.algorithm=algorithm

If the value of algorithm is NULL or an empty string, SHA-1 will be used on the password only.

Default

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.

Example

-- system-wide property
derby.authentication.builtin.algorithm=SHA-512

-- database-level property
CALL SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY(
    'derby.authentication.builtin.algorithm', 'SHA-512');
