Maybe you should at least issue a warning that this action could take some time for now.

Maybe system() or even passthru() will do the job of displaying output (in some PRE tags). No - PHP buffers output and, if using gzip compressed output buffering, this would be an absolute mess to get to work correctly (if even possible). definitely not worth the extremely limited benefit we may get out of it.

Maybe system() or even passthru() will do the job of displaying output (in some PRE tags). Does it matter how long it actually takes? Users tend to becoming nervous if something does not change within 10-20 seconds, so you have to show them their wishes are executed. This ticket's topic should be "IMP seems to be hanging at creation ....". (It is a development and testserver and GPG works very well on that machine, Entropy might be the cause.)

I started the generation process and closed the window by accident. The time I gained by that was good to eat something. ~20 minutes passed and I logged in again to start the process again - to my surprise there were the keys! The only explanation I have is that there is not enough entropy on the server. Is there anything running on that server, more users being logged in etc.? - Advise the user to go eating something while generating takes place This shouldn't happen on a sane system. - or display a popup with GPG's output in order to show him the status. This is probably not possible with PHP.

After having written the bug report I logged in again to reproduce this issue with increased verbosity level of debugging. I started the generation process and closed the window by accident. The time I gained by that was good to eat something. ~20 minutes passed and I logged in again to start the process again - to my surprise there were the keys! In order to ensure everything was do correctly I have logged out and in with another user and started again generating the key-pairs and waited for about 6 minutes - no pair appeared. But there is one instance of GPG running, abviously invoked by IMP. (It ended successfully after ~20 minutes.) Now, as I believe the keys will be generated successfully this time (again), I would recommend you one of the following: - Advise the user to go eating something while generating takes place - or display a popup with GPG's output in order to show him the status.

Works fine here. Try to track down, where it's hanging.

Activate GPG/PGP support and ensure it works by sending some encrypted emails (and receive some). Switch to an other account which has no imported keys and try letting IMP generating some for your. IMP will hang. You will wait forever for any change or new page.
