RE: dbms_obfuscation package

FWIW:   This is something I played with a long time ago:

DECLARE

   v_input_string        VARCHAR2(32)    := RPAD('STRING TO BE ENCRYPTED', 32, ' ');
   v_key_string          VARCHAR2(32)    := RPAD('JOXERTHEMIGHTY', 32, ' ');
   v_encrypted_string    VARCHAR2(2048)  := NULL;
   v_decrypted_string    VARCHAR2(2048)  := NULL;

BEGIN
  DBMS_OUTPUT.PUT_LINE ('String to be encrypted:  ' || v_input_string);

  DBMS_OBFUSCATION_TOOLKIT.DESEncrypt (input_string => v_input_string,

                                       key_string => v_key_string,
                                       encrypted_string => v_encrypted_string);

  DBMS_OUTPUT.PUT_LINE ('Encrypted String: ' || v_encrypted_string);

  DBMS_OBFUSCATION_TOOLKIT.DESDecrypt (input_string => v_encrypted_string,

                                       key_string => v_key_string,
                                       decrypted_string => v_decrypted_string);

  DBMS_OUTPUT.PUT_LINE ('Decrypted String ' || v_decrypted_string);
END;

Ahem...

Yours truly has an article on Oracle and encryption which includes using DBMS_OBFUSCATION_TOOLKIT.

Complete with code.
