Client-Side Encryption

This is a module implementing RSA encryption of data on the client side.
It's currently storing the public key and the cipher text on the front end.
I'm working on storing ciphertext and keys on the backend.

/cse/gen again says that the keys are already generated:

/cse/store encrypts data

Successfully encrypted!

/cse/view Deciphers and displays data

/cse/empty empties the keys locally.
