That sounds good. Another way could be REST if it's easier to implement or still exists?

Okay, something more information to the workflow:
- we have member, which are in a external trusted network (VPN like) where the user is already authenticated, but no public network is avaiable
- we want a way to communicate with the user via mail (PGP) and need a verification for their key
- the idea is, they send us a mail, encrypted to a specific mail adress and we deattach the PGP key with ciphermail, so we have the public key
- now the user can send us via a web form or something like that the ID from his key in the trusted network, so we can validate the pub key received via public internet
