Re: DES and 3DES

Check if either crypt() or mycrypt() [using 3DES] matches, and if either one is right, it must be okay. The odds on the wrong password matching the other algorithm by random chance are, like, too big for my poor brain, but they gotta be pretty high... ----- Original Message ----- From: "Michael Slater" <slaterm@tnet.com.au> Newsgroups: php.general Sent: Tuesday, December 05, 2000 6:27 AM Subject: [PHP] DES and 3DES Hello, I am am trying to write a bit of php code that can take a file containing usernames and encrypted passwords and using the php crypt() function compare them against a user supplied password string. The problem is, that the encrypted passwords come in two different formats. About halfway through the file the encryption method changes from normal DES encryption to 3DES encryption and the php crypt() function does not seem to like this.. I had thought of using mcrypt, but cannot devise a way to switch between the two types automaticly... any ideas ? Michael Slater slaterm@tnet.com.au
