php crypt help

[music_man]

Hi

I am trying to store an email variable in an encrypted format using crypt and then be able to view it decrypted in the administration. I presume that the decryption method used to view the email it can be applied across other functions.

crypt() [php.net] is a one-way string encryption so you aren't going to be able to see the original value once it has been run through this function. There is no "decrypt" function. If you truly need an administrator to be able to see the value "decrypted" then you have to store the value in it's original format, no encryption.

In order to encrypt and decrypt, you'll need the Mcrypt Encryption Functions [php.net].
