OpenRSA is a program to encrypt and decrypt the RSA cipher.
For example if you had a friend you wanted to communicate with through an encrypted chat using the RSA cipher. You could use the following command newusr and then type your friends name whos name is in this case Bob. After that then you need to write your message at /users/Bob/encrypted.txt and Bob's public key at /users/Bob/pubkey.txt. After that you can use the command encrypt and enter Bob to encrypt the contents of /users/Bob/encrypted.txt.
First of all, you need to install git if you don't already have it.
$ git clone https://github.com/TheCodingGuys/OpenRSA.git
$ cd OpenRSA/
$ python3 run.py
