Security Interface
This library provides easy API for authentication and authorization.
Installation
Install with the following command:
$ pip install security_interface
Usage
First of all you need implement IdentityPolicyInterface and AuthorizationPolicyInterface interfaces. For example we can implement JWT Security:
import jwt
from security_interface import IdentityPolicyInterface, AuthorizationPolicyInterface
class JwtIdentityPolicy(IdentityPolicyInterface):
def __init__(self, secret, algorithm="HS256"):
self.algorithm = algorithm
self.secret = secret
async def identify(self, identity):
if jwt is None:
raise TypeError("Please install PyJWT")
try:
return jwt.decode(
identity,
self.secret,
algorithms=[self.algorithm],
options={"verify_exp": True, "verify_iat": True},
)
except Exception as e:
return None
class JwtAuthPolicy(AuthorizationPolicyInterface):
async def can(self, identity, permission):
return permission in identity["scope"]
Create security instance with our implementation
from security_interface.api import Security
jwt_identity = JwtIdentityPolicy("SECRET")
jwt_auth_policy = JwtAuthPolicy()
security = Security(jwt_identity, jwt_auth_policy)
# Checking claim
security.identify(CLAIM)
# Checking permission
security.can(CLAIM, "read")
security.can(CLAIM, "write")
