Description

From koto@google.com on September 02, 2014 17:13:48

In the keyring, for given User IDs we might have public/secret (sub)keys that can only encrypt/sign or verify a message. There is no guarantee that we can encrypt a message for every user id in a public keyring. For example, some keys might have been revoked,expired or just missing.

We should not allow the user to choose a user Chip as a recipient, if we don't have an encrypting key for that user.

Steps to reproduce:

  1. Import the following key - passphrase 'koto'

  1. Try to encrypt the message.
  2. Enter koto+rsa in the recipients list

What happens:
You can choose koto+rsa identity. Encrypting the message will however only encrypt to senders' key, because koto+rsa UID has no public key to encrypt to.

What should happen:
koto+rsa Chip should be a red chip or should not show in the UI at all.
