DES Encryption

[grega]

I use dbms_obfuscation_toolkit.DESEncrypt with a given string and key to produce an encrypted string.

I have a java class which takes the same string and key, does a DES encryption using JEncrypt (

http://www.alongtime.com/index.htm),

and seems to produce a different encrypted string.

Any ideas why this would be happening?

(I'm doing this because I need to take a password encrypted by Oracle and decrypt it within a Java app).

Most password encryptors add what is called a "salt" to the password as they encrypt it, so if you encrypt the same password multiple times you get different results. This is done to defeat dictionary attacks, where an attacker has a huge lookup table. If there is a randomization, that technique is much more difficult.
