Hi There,

Apologies for late response. Did you try passport-jwt package?
var JwtStrategy = require('passport-jwt').Strategy;
var ExtractJwt = require('passport-jwt').ExtractJwt;

And maybe you can create an options object like:
var opts = {};
opts.jwtFromRequest = ExtractJwt.fromAuthHeaderAsBearerToken(); //depends
opts.secretOrKey = config.secretKey;

passport.use(new JwtStrategy(opts,
(jwt_payload, done) => {
console.log('JWT payload', jwt_payload);
}
)));

And if you have specified a login route like this:
router.post('/login', passport.authenticate('saml'), (req, res) => {
var token = jwt.sign({_id: req.user._id}, config.secretKey, {
expiresIn: '1h'
});
res.statusCode = 200;
res.setHeader('Content-Type', 'application/json');
res.json({ success: true, token: token, status: 'You are successfully logged in !' })
});
Let me know if this is what you are looking for.

Thank you Mitesh
thanks for your reply which is good but it answer partially to my request
what I'm looking for is how to create an RTS to post as soap request including the assertion. I'm not very strong in security so forgive me if I don't use the right terminology. in short, after the SSO I need to make a was trust call passing the RST and once I got the RSTR I need to extract the token which I guess is what you wrote above

thanks for your help
