OpenSSL not availble on appengine

[nichochar]

I'm getting the ImportError: cannot import name SignedJwtAssertionCredentials due to the fact that this module only tries SSL with OpenSSL. Unfortunately appengine doesn't have this lib, so maybe there should be a compatibility with pycrypto ?

Looking at this issue it seems SignedJwtAssertionCredentials should work with PyCrypto or OpenSSL. I'm wondering if GAE requires Google's special GAE client library.

Another option might be to add support for AppAssertionCredentials.

Can you confirm you have PyCrypto enabled on your appspot? Looking at the oauth2client code, it seems it should "just work" if PyCrypto is available. https://code.google.com/p/google-api-python-client/source/browse/oauth2client/client.py#44

Eventually you need to convert the PKCS12 file downloaded from the developer's console API. pycrypto has accepted the converted and modified PEM file in my case. See post 20 in the issue, tylertreat has linked.

Yeah we ended up using AppAssertionCredentials

And @tylertreat yes I did have pycrypto, but it wasn't passing the validating test in that file... It's kind of weird and I suspect a modified version of that library on googles appspot...
