简介

jsencrypt是一jquery款字符串加密解密插件。

使用

1.  引入 jquery.min.js 和 jsencrypt.js 文件

2.  HTML

<h2>第一步：获取公钥</h2>
<button id="getKey">点击获取公钥</button>
<hr/>
<h2>第二步：将本地数据加密后，在远程进行解密</h2>
<input id="dataText1" placeholder="本地数据"/>
<button id="sendButton">发送</button>
<input id="dataText2" placeholder="远程解密"/>

3.  调用

(function(window) {
    'use strict';

    var rsa = function(params) {
        $.extend(this.params, params);
        this._init();
    };

    rsa.prototype = {
        params: {
            publicKey: '',
        },

        _init: function() {
            var that = this;
            that.getKeyClick();
            that.sendButton();
        },

        /**
         *  获取公钥
         */
        getKeyClick: function() {
            var that = this;

            $('#getKey').click(function() {
                $.get('testrsa.php', {act: 'get'}, function (result) {
                    result = $.parseJSON(result);
                    // 保存公钥
                    that.params.publicKey = result['publicKey'];
                });
            });
        },

        /**
         *  发送测试数据
         */
        sendButton: function() {
            var that = this;

            $('#sendButton').click(function() {
                var dataText1 = $('#dataText1').val();

                // step1:本地加密
                var encrypt = new JSEncrypt();
                encrypt.setPublicKey(that.params.publicKey);
                var encrypted = encrypt.encrypt(dataText1);
                console.log(encrypted);

                // step2:服务器上私钥解密
                $.get('testrsa.php', {act: 'data',dataText: encrypted}, function (result) {
                    result = $.parseJSON(result);
                    console.log(result['code']);
                    console.log(result['decrypted']);
                    $('#dataText2').val(result['decrypted']);
                });
            });
        }
    };
    window.rsa = rsa;
})(window);
