Programming 9 - One Time Pad Encryption

Does anyone know how to do the reverse blowfish encryption? I solved the sudoku part, but I can't figure out the encryption. Help!

IIRC, this is a pain in the ass. I don't think I ever got the provided php version working and I ended up rewriting it. I'll post that part if I can find it but that might be cheating. Running into multiple-solution sudoku was also annoying. :)

The link to the blowfish.php doesnt work, or so it seems. Is this some kind of extra difficulty that is plannend or is it just a dead link?
Can someone point me in the right direction?
Thanks

The link https://www.hackthissite.org/missions/p ... wfish.phps is broken.
Are the administrators aware?

I'm also running into this problem.
I wrote a simple sudoku solver, but now I need to know how the encryption algorithm works to be able to write the decryption part.

I found a post from 2015 that has an encryption implementation in C that I ported to Groovy, but it seems that it is missing an important step as it only implements the block_encrypt() function and not the top-level encrypt() function.
It would be nice if the administrators could put up the original PHP implementation
