jwt — JSON Web Tokens

Requires: OpenSSL (auto-installed via minks install jwt)

#include "jwt"

HS256 sign, verify, and decode. No libcurl dependency — only OpenSSL is needed.

Method Args Out Description
JWT:Sign payloadJson, secret String HS256-sign payload JSON → token string
JWT:Verify token, secret Boolean true if signature valid and exp (if present) has not passed
JWT:Decode token String {"header":{...},"payload":{...}} — no signature check
JWT:Claims token String Payload JSON only — no signature check
JWT:Header token String Header JSON only — no signature check
JWT:Expired token Boolean true if exp claim is in the past — no signature check

Throws JWTException on a malformed token. See Object — Exception.

Var:String token;
Var:Boolean ok;
Var:String claims;
Var:Boolean expired;

JWT:Sign("{\"sub\":\"user42\",\"exp\":9999999999}", "my-secret", token);
Konsol:Print(token);

JWT:Verify(token, "my-secret", ok);
Konsol:Print("valid: ${ok}");    // valid: true

JWT:Claims(token, claims);
Konsol:Print(claims);            // {"sub":"user42","exp":9999999999}

JWT:Expired(token, expired);
Konsol:Print("expired: ${expired}");   // expired: false

// Use with Curl:
Var:String response;
Curl:SetHeader("Authorization", "Bearer " + token);
Curl:Get("https://api.example.com/profile", response);

Building from source

Only OpenSSL is required — libcurl is not needed. On MSYS2, OpenSSL is typically already present as a dependency of curl — check with pkg-config --exists openssl && echo found before installing.

Platform Command
Debian/Ubuntu sudo apt install libssl-dev
Fedora/RHEL sudo dnf install openssl-devel
macOS brew install openssl
MSYS2 MINGW64 pacman -S mingw-w64-x86_64-openssl
MSYS2 UCRT64 pacman -S mingw-w64-ucrt-x86_64-openssl
MSYS2 CLANG64 pacman -S mingw-w64-clang-x86_64-openssl
MSYS2 CLANGARM64 pacman -S mingw-w64-clang-aarch64-openssl

The Makefile auto-detects via pkg-config. For native Windows, download Win64 OpenSSL and override OPENSSL_DIR if not using the default (C:/OpenSSL-Win64):

make -C jwt_plugin OPENSSL_DIR="C:/your/openssl"
