title: Decrypt AES 128 on T-SQL
body: <p>I have a database that is currently using AES 128. The database has about 8 million records, and what the client wants is to decode the passwords and hash them instead so the passwords cannot be decrypted. This is a web app with data stored on a remote server. I tried using a web app to do the conversion, but it keeps timing out. Since this is 8 mil, it will take a while to go through all the items, so my next idea was to get SQL do do the decryption and hashing. I could let it run for the next few days.</p>
  
  <p>The problem I am having is that each column has the encrypted password with a unique salt. I can't find a function to decrypt the password using the encrypted password and salt. Is there a function? Even third party? Is there a better way to go about this?</p>
  
  <p>Thanks!</p>
