Sign/encrypt user interaction loop with YubiKey #2507
Description
When using the API ACTION_SIGN_AND_ENCRYPT with a Yubikey it keeps returning a pending intent to scan a Yubikey (and possibly other keys).
Expected Behavior
One or maybe two NFC scans only
Current Behavior
Repeating user interaction to scan Yubikey
Possible Solution
The problem seems to occur here:
https://github.com/open-keychain/open-keychain/blob/master/OpenKeychain/src/main/java/org/sufficientlysecure/keychain/pgp/PgpSignEncryptOperation.java#L578
Steps to Reproduce (for bugs)
- Generate/store key
- Call ACTION_SIGN_AND_ENCRYPT
- Scan Yubikey
Context
I am trying to make sign and encrypt working with a Yubikey for FairEmail:
https://github.com/M66B/FairEmail/blob/master/app/src/main/java/eu/faircode/email/FragmentCompose.java#L1689
Sign and encrypt without Yubikey works properly.
