Alright so MD5 hashing mirc has a $md5 command. It returns Hex 0-9 A-F Data.
Im not sure of mIRC's MD5 algorhitm therefore I couldn't help much upon it + I don't know if mIRC depends on a checksum value. If this was assembly then I would definently be able to help.
There are generic tables that can be used to decrypt the md5 hash however, I would need to know how the $md5 was written into the compilation of mirc.exe
I meant MD5 and SHA to be examples.. I like making my own stuff, and experimenting with things. It's just a way for me to amuse myself.
Also, as for the calculations, using a script that allows the embedding of Ruby code into mIRC.. I've finally made long calculations work.
Thanks for everyone's help, though, and sorry if it seems like wasted time.
