This library is a packaging of the original code from Tom Wu. The original files are available in the original/ folder or on his site.
Updated for the 1.2 release as well as the 1.3 release of jsrsasign.
Using NPM, installing is as easy as: npm install node-bignumber
For help on using this in node.js, have a look at the tests. Here is a simple example on how to generate a new key and use it to encrypt/decrypt a message.
var rsa = require("bigint"); var key = new rsa.Key(); var message = "All your bases are belong to us."; console.log("Message:\n"+message+"\n"); // Generate a key key.generate(1024, "10001"); console.log("Key:\n"); console.log("n:" + key.n.toString(16)); console.log("e:" + key.e.toString(16)); console.log("d:" + key.d.toString(16)); console.log("\n"); // Encrypt var encrypted = key.encrypt(message); console.log("Encrypted:\n" + rsa.linebrk(encrypted, 64) + "\n" ); // Decrypt var decrypted = key.decrypt(encrypted); console.log("Decrypted:" + rsa.linebrk(decrypted, 64) + "\n");
