Poco::JWT

class Token

File Information

Library: JWT
Package: JWT
Header: Poco/JWT/Token.h

Description

This class represents a JSON Web Token (JWT) according to RFC 7519.

To create and sign a JWT (using the Signer class): 

Token token;
token.setType("JWT");
token.setSubject("1234567890");
token.payload().set("name", std::string("John Doe"));
token.setIssuedAt(Poco::Timestamp()));

Signer signer("0123456789ABCDEF0123456789ABCDEF");
std::string jwt = signer.sign(token, Signer::ALGO_HS256);

To verify a signed token: 

std::string jwt(
	"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9."
	"eyJpYXQiOjE1MTYyMzkwMjIsIm5hbWUiOiJKb2huIERvZSIsInN1YiI6IjEyMzQ1Njc4OTAifQ."
	"qn9G7NwFEOjIh-7hfCUDZA1aJeQmf7I7YvzCBcdenGw");

Signer signer("0123456789ABCDEF0123456789ABCDEF");
Token token = signer.verify(jwt);
