 Where possible the B<EVP> interface to symmetric ciphers should be used in
 preference to the low level interfaces. This is because the code then becomes

 PKCS padding works by adding B<n> padding bytes of value B<n> to make the total 
 length of the encrypted data a multiple of the block size. Padding is always
