Sending RSA-SH1 encoded requests?

[rupert-git]

Wondering if it's possible to use RSA-SH1 with this library. The example you've provided for request (Node.js) uses HMAC:

var oauth = OAuth({
    consumer: {
        key: 'xvz1evFS4wEEPTGEFPHBog',
        secret: 'kAcSOqF21Fu85e7zjz7ZN2U4ZRhfV3WpwPAoE3Z7kBw'
    },
    signature_method: 'HMAC-SHA1',
    hash_function: function(base_string, key) {
        return crypto.createHmac('sha1', key).update(base_string).digest('base64');
    }
});

To make it work with RSA, I've tried changing the OAuth.prototype.getSigningKey function to return an RSA private key, and used the following init:

var oauth = OAuth({
    consumer: {
        key: inputData.consumerKey,
        secret: inputData.consumerSecret
    },
    signature_method: 'RSA-SHA1',
    hash_function: function(base_string, key) {
      var buffer = new Buffer(base_string);
      var encrypted = crypto.privateEncrypt(key, buffer);
      return encrypted.toString("base64");
    }
});

But no luck so far. Just wondering if RSA is possible with this library's code - or am I barking up the wrong tree?

@rupert-git seems like you doing at the right place. how about this:

const crypto = require('crypto');
const sign = crypto.createSign('RSA-SHA1');

hash_function: function(base_string, key) {
    sign.write(base_string);
    sign.end();
    return sign.sign(key, 'base64');
}

Thanks @ddo, got an RSA-SH1 request working with your advice :)
Much appreciated!
