md5 is part of dbms_obfuscation_toolkit package

    PROCEDURE MD5(input    IN  RAW,
                  checksum OUT raw_checksum);

    FUNCTION MD5(input    IN  RAW)
        RETURN raw_checksum;

    PROCEDURE MD5(input_string    IN     VARCHAR2,
                  checksum_string    OUT varchar2_checksum);

    FUNCTION MD5(input_string    IN     VARCHAR2)
        RETURN varchar2_checksum;
