I think i may have the wrong area...but this is the first time i have ever tried to use a forum...not too good at it...if anyone could point me to the rite spot...
if i do have the right spot...

is "dunno" in some encryption thing...if anyone knows just how one becomes the other and can explain it a bit it would help...or show me to a website that can help that would be...helpful?
thanx anyway

Pardon me if I start too simple here ... Encryption is just a way of scrambling a message to make it hard for unintended readers to understand and decryption is unscrambling it. Techniques are as simple as substituting one letter for another and about as complex as modern mathematics can get.
A quick Google on "java encryption" will get 454,000 hits with many different encryption algorithms.
I enjoyed The Code Book as an easy very-low-math history of encryption. And Cryptonomicon as very entertaining fiction with some good facts on encryption.

You really need to ask the person who designed the system. Nonetheless, I can give your a couple of clues.
First, the stuff on the left hand of the colon is the encrypted values. It's 16 bytes, which indicates a 128bit hash or possibly even a 128bit block cipher . You can tell the difference between the two by looking at what happens with longer passwords. If it's a hash, no matter how long your input then you'll still get the same length hash. If it's encrypted, then the length will increaase for longer passwords. Try a password of 20 or 30 characters and see. (assumming your system doesn't cut it off at 8 characters or something)
Second, the stuff on the right is probably a salt of some sort. Does the length of this change with the length of the password? It's 5 bytes now, which is the same length as your password. That suggests to me that it might just be a simple XOR onto your password to feed the hash. 5 bits seems an odd length for a hash. But, it's possible. Or maybe it is combined with some bits hardcoded into the code.
Unless you have some serious crypto experience, you won't figure out anything just by looking at the bits. You need to look at the code or ask the person who created the system.
