I developed a website with Joomla 1.7 and Community Builder.
One of the fields of registration is "Credit Card Number". So this is a field confidential, and must be secure (encrypted)
My question is there a plugin or a method that encrypts the account number in the database given after registration.
This field must then be decrypted to be visible in the client information.
For clarification, I want an asymmetric encryption (AES type, for example) if there is a function in PHP I can call it to encrypt the field in the data base after registration, and another function to decrypt the field in page "My Account".
- I can add PHP lines, functions...
I am not an expert in the domain of encryption and security, so anyone have any suggestion please say it.
