Description Andreas Bleischwitz 2011-07-13 15:35:12 UTC 
Description of problem:

A passphrase preseted by gpg-preset-passphrase is expired after "--max-cache-ttl" seconds although it was put into the cache with "requested tty=-1"

Version-Release number of selected component (if applicable):
gnupg2-2.0.14-4.el6.x86_64

How reproducible:
Start the agent, preset a passphrase and try to use it using gpg - this should work without questioning a passphrase.
After "max-cache-ttl" seconds try to repeat the gpg-command - this should fail or ask for a passphrase

Steps to Reproduce:
1. create gpg-key
2. eval $( gpg-agent --allow-preset-passphrase --log-file=/tmp/gpg-agent.log --debug-level=expert --sh )
3. echo "test" | gpg -ase # abort this- just for getting the keygrip
4. search for 40byte keygrip in logfile of gpg-agent
5. /usr/libexec/gpg-preset-passphrase --preset $keygrip
6. enter passphrase
7. echo "test" | gpg -ase -r <your.mailaddr>
8. sleep $max-cache-ttl
9. echo "test" | gpg -ase -r <your.mailaddr>
  
Actual results:
The preseted key is expired

Expected results:
The preseted key is valid forever or until SIGHUP or until --forget

Additional info:
We need the gpg-preset-passphrase funtionality for automated gpg-verify/-decryption which should not have any further user interaction
