Encrypt/decrypt

FeeBle

If a password is encrypt with the fukntion "crypt()" can I decrypt it and if I can how do I do it??

decrypt() I THINK...
But why do you need to decrypt it? You should one-way encrypts passwords with md5() then to compare an entered pass with the real one - encrypt the one they entered!

You just can't decrypt...

If you RTFM you will see that under crypt() it says this..

crypt -- One-way string encryption (hashing)

(ONE WAY STRING encryption) 🙂

Sorry, just thought I'd share hehe

Yes but I read in a noob book that as long as you know the key/salt word you can decrypt it in the same way but the book say it is one funktion "crypt" with is both "encrypt" and "decrypt" and when you uses encrypt you will need a salt/key or else it's going to be randomized and the encryptsen are going to be diffrent everytime but are u using the same salt/key there is going to be a match....
thats just what is says but I haven't got it to work and it is just crypt with works and not encrypt...

Actually, the DES algorithm is a 2-way encryption algorithm.

However the implementation the manual refers to probably is 1-way, perhaps because the salt isnt kept.

In any case, crypt() doesnt have a corresponding decryption function in PHP.

If you want encryption functionality, write your own implementation, or use the mcrypt library
