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

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.
