This article will teach you how to use the RS256 algorithm to implement JSON Web Token (JWT) Authentication and Authorization with Golang, Gin Gonic, SQLC, PostgreSQL, and Docker-compose. Also, you will learn how to use asymmetric encryption (private and public keys) to generate access and refresh JWTs in Golang.
