Trying to understand a bit more about about the RC5 5187 Acc-Client password decryption process

I think the main problem is the length you're providing in the packet. With the structure you defined above, that's 325 bytes + 8 which is the expected 333 bytes (given a junk padding length of 12). Looking at your packet structure snippet though, you're initializing the length at only 314 bytes. I'd try fixing that length and seeing if that helps. *fingers crossed*

A friend reached out and pointed out an obvious stupid mistake I was doing. Was not even using the correct encryption (blowfish). I should have guessed as much. Thanks for your patience Spirited.

Ahhh, yep. That'd do it! Glad you were able to figure it out!

Managed to successfully login using 5187. There are a few packets I need to upgrade and some kind of odd double connection occurring but other than that, it works :).

Great job, and good luck with your other server upgrades!
