Python implementation of the Ruby Signature library (https://github.com/mloughran/signature)

` pip install apysignature`

Client example

`python from apysignature import signature params = {'some'='parameters'} token = signature.Token('my_key', 'my_secret') request = signature.Request('POST', '/api/thing', params) auth_hash = request.sign(token) query_params = params.update(auth_hash) requests.post('http://myservice/api/thing', data=query_params)`

query_params looks like:

`python { 'some'='parameters', 'auth_timestamp'=1273231888, 'auth_signature'='28b6bb0f242f71064916fad6ae463fe91f5adc302222dfc02c348ae1941eaf80', 'auth_version'='1.0', 'auth_key'='my_key' }`

Server example (Django)

`python from apysignature import signature auth_request = signature.Request(request.method, str(request.path), params) public_key = params['auth_key'] token = signature.Token(public_key, private_key) try: auth_request.authenticate(token) except AuthenticationError as e: return HttpResponse('Unauthorized', status=401) # Do whatever you need to do end`
