At attempt will be made to convert them, but if that fails then exceptions will be thrown.\n\n.. code:: python\n\n    httpsig_cffi.Signer(secret, algorithm='rsa-sha256')\n\n``secret``, in the case of an RSA signature, is a string containing private RSA pem. In the case of HMAC, it is a secret password.\n``algorithm`` is one of the six allowed signatures: ``rsa-sha1``, ``rsa-sha256``, ``rsa-sha512``, ``hmac-sha1``, ``hmac-sha256``,\n``hmac-sha512``.\n\n\n.. code:: python\n\n    httpsig_cffi.requests_auth.HTTPSignatureAuth(key_id, secret, algorithm='rsa-sha256', headers=None)\n\n``key_id`` is the label by which the server system knows your RSA signature or password.\n``headers`` is the list of HTTP headers that are concatenated and used as signing objects. By default it is the specification's minimum, the ``Date`` HTTP header.\n``secret`` and ``algorithm`` are as above.\n\n\nTests\n-----\n\nTo run tests::\n\n    tox\n\n\nLicense\n-------\n\nBoth this module and the original module_ are licensed under the MIT license.\n\n\nhttpsig_cffi\n============\n\n15.0.0 (2015-Jan-16)\n--------------------\n\n* Move from PyCrypto to Cryptography.\n* Move to py.test.\n\n\nhttpsig (previous)\n==================\n\n1.1.0 (2014-Jul-24)\n-------------------\n\n* Changed \"(request-line)\" to \"(request-target)\" to comply with Draft 3.\n\n1.0.3 (2014-Jul-09)\n-------------------\n\n* Unified the default signing algo under one setting. Setting httpsig.sign.DEFAULT_SIGN_ALGORITHM changes it for all future instances.\n* Handle invalid params a little better.\n\n1.0.2 (2014-Jul-02)\n-------------------\n\n* Ensure we treat headers as ASCII strings.\n* Handle a case in the authorization header where there's garbage (non-keypairs) after the method name.\n\n1.0.1 (2014-Jul-02)\n-------------------\n\n* Python 3 support (2.7 + 3.2-3.4)\n* Updated tox and Travis CI configs to test the supported Python versions.\n* Updated README.\n\n1.0.0 (2014-Jul-01)\n-------------------\n* Written against http://tools.ietf.org/html/draft-cavage-http-signatures-02\n* Added \"setup.py test\" and tox support.\n* Added sign/verify unit tests for all currently-supported algorithms.\n* HeaderSigner and HeaderVerifier now share the same message-building logic.\n* The HTTP method in the message is now properly lower-case.\n* Resolved unit test failures.\n* Updated Verifier and HeaderVerifier to handle verifying both RSA and HMAC sigs.\n* Updated versioneer.\n* Updated contact/author info.\n* Removed stray keypair in test dir.\n* Removed SSH agent support.\n* Removed suport for reading keyfiles from disk as this is a huge security hole if this is used in a server framework like drf-httpsig.\n\n1.0b1 (2014-Jun-23)\n-------------------\n* Removed HTTP version from request-line, per spec (breaks backwards compatability).\n* Removed auto-generation of missing Date header (ensures client compatability).\n\n\nhttp-signature (previous)\n=========================\n\n0.2.0 (unreleased)\n~~~~~~~~~~~~~~~~~~\n\n* Update to newer spec (incompatible with prior version).\n* Handle `request-line` meta-header.\n* Allow secret to be a PEM encoded string.\n* Add test cases from spec.\n\n0.1.4 (2012-10-03)\n~~~~~~~~~~~~~~~~~~\n\n* Account for ssh now being re-merged into paramiko: either package is acceptable (but paramiko should ideally be >= 1.8.0)\n\n0.1.3 (2012-10-02)\n~~~~~~~~~~~~~~~~~~\n\n* Stop enabling `allow_agent` by default\n* Stop requiring `ssh` package by default -- it is imported only when `allow_agent=True`\n* Changed logic around ssh-agent: if one key is available, don't bother with any other authentication method\n* Changed logic around key file usage: if decryption fails, prompt for password\n* Bug fix: ssh-agent resulted in a nonsensical error if it found no correct keys (thanks, petervolpe)\n* Introduce versioneer.py",
