We have several developers that are trying to encrypt a username/password and be able to decrypt these for various reasons. One such reason is to make sure that the information stored in the database is not readable by individuals not authorized to read it (encrypting) and allow for users to read thier data as needed (decrypt).

I have seen where you can encrypt a string to lets say SHA1, but can not decrypt it once it is encrypted.

Any suggestions would be greatly appreciated. Once we get completed with this class I will share it with all for anyone instreseted.
