[Phpwm] encrypt - decrypt

[alan dunn]

We want to encrypt a string (credit card number) on windows laptops (at 
the moment we are using triple DES). Import the data into the db,  and 
then decrypt in a Linux php environment - using mcrypt.

All our attempts so far have failed. We understand we have to bring the 
initialisation vector with the data - but in Windows that is an array, 
in mcrypt it is a string.

Has anyone else been here, or got any suggestions?

Thanks, alan dunn
