Anyone using GPG or PGP encryption/signatures in your Python apps?

[python]

Curious if any of you are using GPG or PGP encryption and/or signatures
in your Python apps?

In particular are you:

1. clearsigning specific emails?
2. validating clearsigned emails from others?
3. encrypting/decrypting files?
4. generating signatures for files that you are exchanging/posting for
download?
5. what public keyring services are you using?

I'm also looking for recommendations on which 3rd party modules you're
using for these tasks? In particular is there a particular module you
prefer or have concerns about?

Here's my short list of modules that *might* support encryption and
signing in general:

- m2crypto
- pycrypto (standalone or with expycrypto or yawpycrypto wrappers)
- tlslite
- pyme
- evpy
- python-gnupg (by developer of Python's logging module)

Any comments on using the subprocess module to wrap the gpg or openssl
command line utilities? This seems to be a common technique for
encryption and signing solutions and appears to the technique used by
python-gnupg (for example).

Thank you,
Malcolm

I used python-gnupg successfully to create some Django utilities for
sending encrypted email.

You can grab the source code at http://github.com/stephenmcd/django-email-extras

I use pyme to create and check save file signatures.

5. what public keyring services are you using?

None

pyme works great with Linux.
However, I have never installed it on a Windows system.
