Project Description

Am looking for a very simple set of methods:

1: [url removed, login to view] or C# based (prefer [url removed, login to view] but C# is ok) for:

a. Encrypting a string message with a RSA public key

b. Decrypting/Verifying a message encrypted with a RSA private key using the public key.

2: PHP based functions to:

a. Decrypt a string message with a RSA private key (string encrypted with method 1a)

b. Encrypt a string message with a RSA private key (to be decrypted by 1b).

I would also like methods for the reverse created as well, in case they are ever needed - [url removed, login to view] encrypting with private key and a PHP function to decrypt with private key.

I would also like the coder to include instructions on how to secure this communication using a 3rd party public/private key pair.

This should be a very simple project for someone with experience in RSA cryptology, but the successful conclusion of this project will lead to another larger project in a related area (application security). This is a necessary first step.
