 * I’m trying to find a plugin to encrypt user registration fields that I select.
   I want to encrypt the data the same manner that WordPress encrypts password fields.
 * I want to be able to select fields (such as First Name, Email Address) by check
   box and encrypt the data in the database just like the password field.
 * This way I can protect sensitive information in my database in case there is 
   a breach of security. It would also be okay if I could encrypt all fields, too.

 * You might be able to encrypt the fields and decrypt them on the fly using filters.
   However once encrypted you would not be able to decrypt them without also storing
   the encryption key somewhere that’s accessible to the code which would pretty
   much defeat the purpose of encrypting them. Therefore I do not believe what you
   want to do is possible.
 * The password is not retrievable from the database. It is only compared against
   to see if the entered password matches that value when the same encryption process
   is applied to it.
 * You can see the password code WP uses at /wp-includes/class-phpass.php

 * Thanks for the information. I still need it for PCI Compliance. I need to have
   selected fields encrypted. I have several sites and want a plugin to do it so
   I can repeat the process.
 * I have sites that need common personally identifiable fields encrypted too, in
   case someone hacks, tarballs, and downloads the anynamedatabase.sql file.
 * I can forgo editing the database. If the field data gets lost or needs to be 
   re-entered, I have the ability to message the customer that they need to update
   the information in their account.
 * Some example fields that I need encrypted are:
    - First Name
    - Last Name
    - Address
    - Phone Number
    - Cell Phone Number
    - Email Address
 * I have some workers that really don’t need to be in the database anyway(lol).

 * There’s no point in storing the data if you can’t use it. You wouldn’t be able
   to send them emails or see their name or number without being able to decrypt
   it. Since you would have to decrypt the data to use it you would have to store
   encryption keys somewhere and this could make things tricky.
 * Here is a pretty good post with some ideas: [http://security.stackexchange.com/a/12334](http://security.stackexchange.com/a/12334)
 * You might be able encrypt/decrypt using hooks in the WP API if such hooks even
   exist. I’m not even sure if they do since I’ve never tried it. Although I have
   been looking for plugin ideas so I can make some free as well as premium plugins
   so maybe I should look into it and see. Maybe I could even invent a relatively
   secure way to deal with the keys.
 * Since you are going for PCI Compliance hopefully you have a server which is setup
   properly as well.

 * That would be great if you could. Keep me in the loop. I’d definitely buy it.
   I searched for ENCRYPT USER REGISTRATION and ENCRYPTION but found nothing except
   GRAVITATE in the WordPress Plugins repository.
