New submission from Dodain <[email protected]>:
The signature (SHA256 of HMAC Digest) calculated using hmac library doesn't
match the signature calculated using jwt library. The singature calculated
using JWT is the right signature.
The signature with JWT library is VXG8L0SEY3wo5hdAznbvxWXDbhNtuOd7PaZOhzZn_HQ
Whereas the signature with hmac library is
SHR3SSe+8+X8eBw/H+CUc6f5KyXmuONfprdttjeQrwQ=
Since only one file can bu attached so I am inlining the code for finding jwt
signature with jwt library. The code for HMAC library is attached.
import jwt
public = "1234"
print (public)
print jwt.encode({"login":"admin"}, key=public, algorithm='HS256')
