It is not appropriate for us to have several public-private-keys.

Can GnuPG be downloaded on a virtual machine so, that, if one user on VM
generates a pair-key, this pair-key will be also the keys of other user of
this VM? So they all will be able to decrypt files using one private-key..?

How to set it like that, if this is possible.
