Chapter 6 Oracle Encryption

create or replace function get_key
    p_seed        in varchar2 := 'Seed'
return raw
    v_key_raw  raw (2000);
    v_seed_raw raw (2000);
    v_seed     varchar2(2000) := p_seed;
    v_seed := rpad(v_seed, 80);
    v_seed_raw := utl_raw.cast_to_raw (v_seed);
        which=> 1,
        seed => v_seed_raw,
        key  => v_key_raw
    return v_key_raw;

This function will return a different and randomized key every time it is called.

The Encryption Process

The next step is to create a function that returns the encrypted value from an input value.
