Examples of org.apache.openejb.cipher.PasswordCipher

org.apache.openejb.cipher.PasswordCipher
Implementations of {@link org.apache.openejb.cipher.PasswordCipher} allow to encode and decode passwordsused to connect to a database.
Several implementations may exist, as several encryption algorithms may be supported. One-way encryption algorithm (hash) can't be used as we need to give a plain password to the database. {@link #encrypt(String)} method is notmandatory as we don't need to encode a password, but it's useful to get the encrypted value for a given plain text password. In the case you have implemented both methods, you can use the PasswordCodec command line tool to encode/decode a password.

        // try the FQN of the target codec
        assertNotNull(PasswordCipherFactory.getPasswordCipher(PlainTextPasswordCipher.class.getName()));
    }


    private void assertPluginClass(final String pluginName, final Class<? extends PasswordCipher> pluginClass) throws SQLException {
        final PasswordCipher plugin = PasswordCipherFactory.getPasswordCipher(pluginName);
        assertNotNull(plugin);
        assertTrue(pluginClass.isInstance(plugin));
