Hi Experts,

Just a general question about encryption.

Assuming a CA has issued 2 users (A and B) valid certificates.

Can A encrypts a file and specifies that only B can read it? If yes, how
could this be done? If no, any alternate way to do this?

Also, what if A encrypts a file and want a group of users (have valid
certificates from the same CA) to be able to read it?

Thanks a lot!
