xml-cryptoXML 数据签名和加密

xml-crypto 是一个 Node.js 的扩展用来实现对 XML 数据签名和加密。

示例代码：

    var SignedXml = require('xml-crypto').SignedXml

      , FileKeyInfo = require('xml-crypto').FileKeyInfo  

      , fs = require('fs')



    var xml = "<library>" +

                "<book>" +

                  "<name>Harry Potter</name>" +

                "</book>"

              "</library>"



    var sig = new SignedXml()

    sig.addReference("//*[local-name(.)='book']")    

    sig.signingKey = fs.readFileSync("client.pem")

    sig.computeSignature(xml)

    fs.writeFileSync("signed.xml", sig.getSignedXml())
