Is there a way to encrypt a field within a table? I want to put usernames
and passwords within a database table, but want to make it secure as much as
possible. Any tips on how I should do that?
 
You can not make it secure. You can make it confusing, and thats just
about it. Don't store sensitive information of any importance in a
homebrew security like that, especially if the database is used in a
high-risk environment (like internet).
You can think of a number of simple algorithms. Multiply ASCII values by
5 and store those. Shift letters by their offset from A. Reverse the
letters, replacing A with Z and so on.
This will protect the information from view. But it is not going to
protect it from a hacker. If you want a meaningful security, you need to
move to a server based database.
