Hello,

I have a system that uses certain id info. This info is stored in a session cookie in MD5 format. At certain parts of the code I need to update or insert to MySQL DB with that id info value in cleartext. Is this possible?

If so, how to put this to a sql query?

$sqlquery = "insert into x_table (team_id,number,) values ('$team_id','$number')

$team_id is the MD5 formatted cookie value and I need to put it to the x_table column team_id in cleartext.

Thanks a lot

MD5 values are hashes, not encryptions. There's nothing to "decrypt". It's good for storing the results of some value and than when the person sends the MD5 back at a later point you can make sure it still matches the desired value by re-hashing the original value again.
