I'm at the same point. Reverse engineered the psw so that when my code is encrypted I get the same as the provided encryption but won't work in the psw box...

Make sure you double check and count all the characters. I've seen people have all but the last character or something similar wrong.

Hi all,

First off, I'd like to thank everyone for all the tips. Very helpful indeed....

Can someone please help me confirm my reverse engineering is correct because the page isn't accepting it just like a few others. I have double checked and have confirmed the amount of characters I'm entering, I have tried copy and paste from the box above and still I'm getting error results.

Hello everyone,

As someone in school for programming, this is definitely fun and great to learn. However, I'm encountering the same issue as others. I've successfully decrypted the password, but the password field won't take it. It is the correct amount of characters and it has all been cross-checked. The decrypted password I have, when encrypted = the given encrypted password. Please message me with assistance.

I just checked the mission, it's working fine. What you put into the password field isn't the whole or correct password. Are you sure you understand the encryption? Reply once more to PM me (you need 2 posts for that) and I'll check your answer with mine.

I'll cross check again. I could be missing something, but from what I've read, I did the decryption correctly.

I found the correct password by reverse-engineering the encryption. To do so I programmed a Java app. Was there any way that did not involve direct programming?

The first time I did it in Excel (yeah, I know) and once I did it easily by hand, using a table. So I guess there are lots of ways to do it. That aside, once coded a program is the fastest way to do it and most useful as exercise.

Alright, thanks :)
I would have expected that there would be a way to fetch the decrypted password without decrypting the encrypted version. But if you say that the only way is to actually decrypt ourselves, then...

That is how most cryptanalysis works, deduce the corresponding plaintext message from a given ciphertext. Not all these challenges are to only subvert a web application, you know :)
