saml-encoder-decoder-js

Routines assembled to encode and decode SAML 2 assertions in Node.js

Installation

To use these routines you first need to install the dependency:

npm install saml-encoder-decoder-js

Using the module

Once the module has been installed, require it into your application:

var saml = require('saml-encoder-decoder-js');

At that point, you can pass your SAML request or response XML to the redirect or POST binding encoding routines.

saml.encodeSamlRedirect(xml, function(err, encoded) {
  if (!err) {
    console.log("Redirect encoded string", encoded);
  }
});

saml.encodeSamlPost(xml, function(err, encoded) {
  if (!err) {
    console.log("POST encoded string", encoded);
  }
});

If, on the other hand, you need to decode previously encoded data, you would handle that like this:

saml.decodeSamlRedirect(xml, function(err, xml) {
  if (!err) {
    console.log("Redirect decoded XML", xml);
  }
});

saml.decodeSamlPost(xml, function(err, xml) {
  if (!err) {
    console.log("POST decoded XML", xml);
  }
});

Demo code

Two demo applications are included to show how the code works. Those are demo-redirect.js and demo-post.js. Each takes some XML, encoded it, and decodes it back to its original state.

The unit tests in the test folder will also provide insight into how the code works.
