To use the dbms_crypto.encrypt function in Oracle, you need to follow these steps:

  1. Start by opening SQL*Plus or SQL Developer and connecting to your Oracle database.
  2. In SQL*Plus or SQL Developer, execute the following PL/SQL code to encrypt a value using the dbms_crypto.encrypt function:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
DECLARE
  l_encrypted_data  RAW(2000);
BEGIN
  l_encrypted_data := dbms_crypto.encrypt(
                        src => utl_raw.cast_to_raw('YourValueToEncrypt'),
                        typ => dbms_crypto.des3_cbc,
                        key => utl_raw.cast_to_raw('YourEncryptionKey'),
                        iv  => utl_raw.cast_to_raw('YourInitializationVector')
                      );
  DBMS_OUTPUT.PUT_LINE('Encrypted Data: ' || l_encrypted_data);
END;


Replace 'YourValueToEncrypt' with the value you want to encrypt, 'YourEncryptionKey' with the encryption key, and 'YourInitializationVector' with the initialization vector.

  1. Run the PL/SQL block to encrypt the value. The encrypted data will be displayed in the output.


Please note that you should store your encryption key and initialization vector securely and should handle encrypted data carefully to ensure data security.
