SHA512 is supposed to be more secure because there's less room for collisions - after all, it's a 128 character string in the end. By the way - technically speaking, this is hashing, not encrypting.

BWAHA! Just messin with you. But that would be kinda sick... though highly impractical for most applications... But still sick

My Contributions	To nip an misconception in the bud right away: md5 (as well as the SHA1 and its variants) is not a means of encryption, but a cryptograhic hashing algorithm.

Encryption indicates that it can be undone. Yours, Shane~ This post has been edited by ShaneK: 3 Nov, 2009 - 08:54 PM

D.I.C Head Joined: 4 Dec, 2008 Posts: 113 Thanked: 2 times My Contributions	I think noorahmad(the topic starter) meant hashing instead of encrypting. I most of the time use md5 with password and a hash(random key) example hash = 5(d (random) password = test passwordmd5 = md5(testhash); in php(of course in this example the hash isn't being calculated randomly) CODE $hash = "5(d"; // (random) $password = "test"; $passwordmd5 = md5($password.$hash); This post has been edited by nightscream: 5 Nov, 2009 - 08:06 AM
