How to implement RSA cryptography to vb.net ?

Question

In advance forgive my bad english

I will make an application that will implement RSA cryptography with vb.net.

So, the flow of the application that I will make is, to protect an excel file, by implementing RSA cryptography.

The application algorithm is:

1. Upload excel file
2. Enter your username and password
3. Then the file is encrypted, and the excel file will be an .encrypted file
4. And if you want to restore a file that has been encrypted, it must be decrypted.

thank you, can you guys help me by giving references or something?
thank you very much for your time.
