RSA XML Decrypter

RSA XML Decrypter for Node. Decrypt a string by private RSA XML C# key in Node.js.

Simple Example

Single key decryption with base64 encoded key.

var RSAXML = require('rsa-xml'),

// base64 encoded private rsa xml key

Install

npm install rsa-xml --save

API

RSAXML([key, [container]])

Create an empty RSAXML Object or import a key with optional key and container parameter.

importKey(key, [container])

Import a private RSA XML key as plain text string, base64 encoded string or in PEM format. The optinal parameter container can handle different key decryptions.

decrypt(value, [container], [encoding])

Decrypt any value by match the key. value must be in base64 or buffer format.
