A very simple library to help generate signed requests.
pip install apysignerFor a GET request
>>> import apysigner
>>> private_key = 'UHJpdmF0ZSBLZXk='
>>> url = 'http://www.example.com/api-endpoint?q=find+my+thing'
>>> apysigner.get_signature(private_key, url)
'zMxf77eY-xuORInBIA0azhxHPg2bzhsjz-huP-OuYKk='For a POST request
>>> import apysigner
>>> private_key = 'UHJpdmF0ZSBLZXk='
>>> payload = {'do': 'something', 'name': 'Johnny'}
>>> url = 'http://www.example.com/api-endpoint'
>>> apysigner.get_signature(private_key, url, payload)
'CFNmvPrjW_Z1x5XO-tQzJzhs6GjeJH0k0SxOuuhJ3YA='Just the basics to create the HMAC signature. You'll need combine this with other things like actually adding the signature on the URL and making the request, but those responsibilities intentionally live elsewhere.
See the django-request-signer project for examples if you need the rest.
