EasyGnuPG

[Keith Mallen]

Sorry to butt in here but in my first post to the list I mentioned that
I was attempting to use FreePascal/Lazarus to interface with GPG via the
command line but whilst I had managed to get it working with OpenSSL
attempting the same methodology on GPG resulted in a 'hang'.

Now I realise I am a novice and whilst Lazarus is supposedly
cross-platform the documentation for Lazarus is hard to interpret
presumably because I am a novice but Lazarus is Pascal and cross
platform and it is Pascal so I would hope more understandable to knuckle
scrapers such as myself.

Someone recently asked about using FreePascal under Windows but made
mention of using a DLL. As far as I am aware FreePascal should give you
a 'direct' command line interface on any platform. I'll be rubbish here
but scratching my head about DLLs reminds me of when I was looking into
'keyloggers' which, under Windows, require a hook into the system if you
wish to capture data across running applications...

Honest I was trying to catch out a 'Microsoft Support Person' who wanted
to fix my computer over the phone.

Anyway, for what it might be worth..

Yes I hate myself already for dropping that one on you with no
explanation but basically it is a GUI that interfaces with OpenSSL via
the command line in order to generate multiple key pairs. As I say
similar does not work on GPG but it would seem that if you can get
access to the command line interface for GPG in a similar manner then,
being naive, it could be a solution

Just floating one

For that we need to be encouraging hackers and tinkerers to experiment with novel interfaces; and this is best done by giving them the software equivalent of Lego rather than Meccano.

If I can't take what I've learned from using the command line for years and apply it (safely) to writing a modest shell script, I'm going to think long and hard before taking the time to learn a Python API. At the very least, any feature accessible through an interactive interface should have an equivalent command line option, so that all interactive operations can trivially be automated. Thought should also be given to whether wrapping all functionality in a single binary with thousands of options is the best interface to present to even expert command line users (again, OpenSSL is another offender).

I wanted to write a small script for my technically-proficient but non-cryptography-expert users so that they could easily manage gpg private keys without me worrying that they'd screw it up; and I ended up with a fragile interface very similar to his that needed to be completely refactored using gpgme. Just interfacing with gpg was the most difficult part of the process; the logic that I built on top of it was easy by comparison. This is the wrong way around.
