Sign data using symmetric-key algorithm encryption
ska
Lets you easily sign data, using symmetric-key algorithm encryption. Allows you to validate signed data and identify possible validation errors. Uses sha-(1, 224, 256, 385 and 512)/hmac for signature encryption. Allows to use custom hash algorithms. Comes with shortcut functions for signing (and validating) dictionaries and URLs.
Key concepts
Hosts, that communicate with each other, share the Secret Key, which is used to sign data (requests). Secret key is never sent around.
One of the cases is signing of HTTP requests. Each (HTTP) request is signed on the sender side using the shared Secret Key and as an outcome produces the triple (signature, auth_user, valid_until) which are used to sign the requests.
signature(str): Signature generated.auth_user(str): User making the request. Can be anything.valid_until(float|str):
