how to encrypt using one way and tow ways encryption

i really need your help on encryption using one and two ways encryption.

I have a log in form where the user should put their user name and password , To pass security a user must provide their UserId. That UserId must then match the UserId on record in the file XXX.sys that is located in the \User\ directory of the user’s USB drive. That file includes the user’s UserId and Passcode separated by a comma and written using the three digit ASCII code for a character. A one way encryption code should be included.

I'm storing my data in a text file called XXX.sys

If the user passes the security check, they are presented with their profile data. The user can change their profile in the security file. The data in the profile should be written in ASCII code and encrypted prior to converting to the ASCII Code. we should use two ways encryption.

I hope it's not that hard and I really waiting for your help.
