AES Encryption

Hello,

I am very new to Yii, but very excited about all the possibilities I see.

I am building an application where several of the fields require encryption (social security number, etc.). In my old, procedural PHP code, I was able to do this when extracting an encrypted field value from MySQL to display in a form:

AES_DECRYPT(insuranceSubscriberSSN,’$key_string’) as insuranceSubscriberSSN

I have looked through the documentation and the forums but have not found a good exmaple of how this works (at least, one that I kind understand).

I would very much appreciate some guidance and examples of the best ways to encrypt and decrypt a couple of fields.

Thanks very much,

Christopher
