Node.JS bindings for PolarSSL, a clean, lightweight crypto library.
PolarSSL is a lot easier to reason about than OpenSSL, and has a nicer API that
can be exposed in node with less abstraction. Hopefully this module will be able
to form the base of an alternative for the built-in crypto and tls modules.
Right now everything here is very very fluid. API's might change with a moment's notice, and the version of this module on npm will likely be out of date. Please clone directly from git://github.com/deoxxa/node-polarssl.git if you want to see how things are doing.
Most of this stuff mirrors the core crypto api, so take a look at the official docs for more details. If an implemented method in this module doesn't behave as specified in the official docs, it's a bug. There are some additional methods as well, so read through this list for the whole story.
var cipher = polarssl.createCipher("ARC4-128", key=Buffer("..."), iv=Buffer("..."));This is a duplex stream - write cleartext in, get ciphertext out.
var cipher = new polarssl.Cipher("md5");cipher.update(Buffer("this is some data"));cipher.updateAsync(Buffer("this is some data"), function(err) {
if (err) {
return console.warn(err);
}
});var data = cipher.final();cipher.finalAsync(function(err, data) {
if (err) {
return console.warn(err);
}
console.log(data);
});var decipher = polarssl.createDecipher("ARC4-128", key=Buffer("..."), iv=Buffer("..."));This is a duplex stream - write ciphertext in, get cleartext out.

});var hash = polarssl.createHash("md5");This is a duplex stream - write data in, get digest out on end().
