Userid and Password strings must be encrypted/decrypted with industry standard crypto functions. The symmetric key (passphrase) - needed to encrypt/decrypt the userid and password - is a string variable set by the caller of encrypt/decrypt methods described below.
I need 4 small components:
1) A simple C# GUI which has input fields for the Userid, the Password, and the Passphrase and a button labeled 'write key file'.
2) A class coded in C#, which takes the 3 input values and writes the encrypted Userid/Password into a key file to disc. The name of the key file is '[url removed, login to view]'
3) A class coded in C#, with a setter method for setting the Passphrase, and getter methods for the clear-text Userid/Password retrieval.
4) Same as 3), but coded in JAVA! Must be compatibel with the key file written by C#.
In order to test components 3) and 4), a simple command-line executable is good enough.
All source code must be handed out to me so that I can recompile and build all components myself.
I am not a security specialist, so if you can't make sense of my description above, maybe you ar not the right person to bid.
This project is very urgent!
