Hello, I'm writing a FTP automated server around Quick'n Easy FTP server, and, i would need to dynamically update the USERS.XML file via code. But for that to work i would need to know what algorithm has been used to encrypt (or hash) the password. I know it's not md5, And I thought for a while it was something like : CryptedletterN=(StringLenght$+letterN+N) for N=0 to (StringLenght$-1) , but it seems a bit more twisted. I'd really appreciate if the developper could give me at least a hint. Thanks in Advance LoupV
