passing information among several users
Hello,
Here is what I am trying to do in my environment.
I have 6 users: maseruser and user{A,B,C,D,E}
Masteruser will be generating data and I would like userA and userC be able
to decypt the data and others not to. However, in the future I would like
to add userE to decrypt the data and remove userA (any old data she has is
fine). I was wondering how I can achieve this using gpg

Make also 6 keypais for each user.

Encrypt it to the public key of users A and C.

Encrypt the new messages only to the keys of C and E.

The eaqsiest way is to define a group in gpg.conf:
group receivers=01234567 ABCDEF89
where 01234567 and ABCDEF89 are the key ID's of the receivers.

Sure you can do this.
Or do you want to know how?
1.) get gnupg software. http://gnupg.org/
Install it, generate your keys and your revocation certificate (you
never know when you will need ont.
2.) Upload your public key to a keyserver.
3, Have A, and C do the same.
3a.) If you want to anytime, have B and D do it too.
4.) When you want to send data get the public keys for A and C.
5.) Encrypt these data with the public the public keys of A and C.
Am I missing something?
