I need to sign the payload:
{"key": "cnc6666666666666", "iat": 1599999999}
With ed25519 seed:
"CNC88888888888888888888888888888"
Output need to be in jwt specification:
eyJhbGciOiJFZDI1NTE5IiwidHlwIjoiSldUIn0.eyJpYXQiOjE1OTk5OTk5OTksImtleSI6ImNuYzY2NjY2NjY2NjY2NjYifQ.RJzhQwRI6g0YZg-Mh201G7aEGcpxm8vN8wf-rgpK6UySeMKRgUHzZV6WLxc93PptrKNb4CLW8XQo48OYR-stDw
This signing need to be done using python3 codes.
I am experienced in this field as I did some projects in uni that needed cryptography, as you described it. Signature and hashing. I think I know how to do your project. And If you wanna collaborate, I will make it work.
