md5 keys should be marked as unusable (e.g. when composing mail)

Reported by steve | March 31st, 2015 @ 03:15 PM | in 0.5 (closed)


  • use a key with MD5 (weak key) as public key in GPG Keychain
  • compose new mail in mail.app
  • "To:" is the email from that key


  • Mail.app shows enabled encryption button
  • When sending the mail, an error is shown that encryption is not possible


  • encrypt button should be disabled
  • it is not good UX to compose a long mail only to discover you can not encrypt it upon trying to send it
