But can I have multiple encryption subkeys, with encryption subkeys
associated with UIDs? I though one subkey per UID only works for signing.

I do not trust the computer at university with the secret key used to
decrypt my private mail. I did set up that computer myself, but we have
burglars breaking into the offices every few years, many people have
keys to the office, etc.

Still, I want  to be able to read any encrypted mail sent to my
unversity addresses on the computer at university. And I want to use
encryption, since the mails might contain sensitive information, such as
exams, grades, etc (and the mail servers are maintained by students).
