Authentication in Golang With JWTs Go is an excellent choice for building fast and scalable API's. The auth_jwt_key_file directive tells NGINX Plus how to validate the signature element of the JWT. If no authentication is needed,. Its only relationship to HTTP is that its handshake is interpreted by HTTP servers as an Upgrade request. Because of this, we recommend that you maximize protection by signing request headers and body, making HTTPS requests to Amazon S3, and by using the s3:x-amz-content-sha256 condition key (see Amazon S3 Signature Version 4 Authentication Specific Policy Keys) in AWS policies to require users to sign Amazon S3 request bodies.
