Re: dbms_obfuscation_toolkit input length

Hello, Hanne

I've attempted the same on a database with UTF-8 charset. I thnik that dbms_obfuscation_toolkit.desencrypt does not check the length of the string but the number of bytes.
You can verify the bytelength of your input_string with vsize, e.g. select vsize('äöüÄÖÜß') from dual
If you can pad the input_string to a vsize of 8, 16, ..., then dbms_obfuscation_toolkit.desencrypt will handle it accordingly.
