RSA: Encrypt and decrypt data with RSA public keys

This class is a pure PHP implementation of the RSA public key encryption algorithm.

It can generate the public and private keys from two prime numbers.

The public key should be used to encrypt the data. Only the private key can be used to decrypt the data encrypted with the public key.

It has also digital signature functionality.
This recommendation solves the problem.
This recommendation does not solve the problem.

There are severals manners to achieve this goal.But if you learn more about user authentification and rsa ,you can implement a basic system where user password can be alternatively public or private key to access some specific content.For example, an user A send a message to an user B.A simple way to encrypt this message end to end is to encrypt this message with the user A password as private key and User B password as the public key before insert it in the database,then you just need to check if it's really user B who tried to read the message,if true you allow by decrypting with public key or if it is user A ,else you don't decrypt it. This way you can't yourself read this message because you are not supposed to know user password.Try the package above to know how to implement a rsa feature in pure PHP then you can try to do an app just like what i say but i don't say it is the optimal or best way.This is just to give you an implementation example as you want to knoW how to do it...
