Symptoms
When you use DBMS_CRYPTO for encryption and decryption, you get the below error:
SQL> create or replace function encrypt(v_string in varchar2) return varchar2 is
2 encrypted_raw RAW (2000);
3 encryption_type PLS_INTEGER := SYS.DBMS_CRYPTO.ENCRYPT_DES + SYS.DBMS_CRYPTO.CHAIN_CBC + SYS.DBMS_CRYPTO.PAD_PKCS5;
4 v_key raw(128) := utl_i18n.string_to_raw( 'artos0011', 'AL32UTF8' );
5 begin
6 encrypted_raw := DBMS_CRYPTO.ENCRYPT
7 (
8 src => UTL_I18N.STRING_TO_RAW (v_string,'AL32UTF8'),
9 typ => encryption_type,
10 key => v_key
11 );
12 return UTL_I18N.raw_to_char(encrypted_raw,'AL32UTF8');
13 end encrypt;
