title: 128-bit PHP Encryption & Decryption of Data
body: <p>I have a client who requires all of the data stored in the MySQL database to be encrypted with 128-bit encryption.</p>
  
  <p>Assuming that before all data is inserted into the DB, a PHP function is run to encrypt it. Then, when I pull the data from the database, I run a decryption function to spit out the original text/info.</p>
  
  <p>Can someone point in me in the right direction. I understand that the functions will use a shared/common key to encrypt and decrypt, but what makes it 128bit? Are there prebuilt functions in PHP that do this?</p>
  
  <p>Appreciate any suggestions.</p>
