String Signer
This module was created to sign strings.
It's only uses building libraries, therefore, it has no external dependency. It is also lightweight and thread-safe, which makes it ideal for use in services and microservices.
The signed string respects the following format:
string:hash_algorithm
Installation
pip install String-SignerTypical usage example:
Sign session
string_signer = StringSigner("My Secret")
session_id = "b801692b-135f-40ff-8f7e-016dc7748c45"
session = {"user_uuid": "67fa3e17-4672-4036-8184-7fbe4c097439"}
encoded_session = base64.urlsafe_b64encode(json.dumps(session).encode()).decode()
signed_session = string_signer.sign(encoded_session)
redis.set(session_id, signed_session)Unsign session
string_signer = StringSigner("My Secret")
session_id = "b801692b-135f-40ff-8f7e-016dc7748c45"
signed_session = redis.get(session_id)
encoded_session = string_signer.unsign(signed_session)
session = json.loads(base64.urlsafe_b64decode(encoded_session).decode())Test Coverage
