Spice-HTML5 use sm-crypto-plugin-spice-html5

插件的使用集中在 spice-html5 连接 spice-server 过程中，包括 SpiceLinkReply 处理 server 消息，以及 password 口令加密发送过程中。

环境搭建

首先是搭建 sm-crypto-plugin-spice-html5 服务

git clone https://github.com/Sovea/sm-crypto-plugin-spice-html5.git

cd sm-crypto-plugin-spice-html5

# 安装依赖
npm install

# 安装 node-gyp
npm install -g node-gyp

# node-gyp 生成配置
node-gyp configure

# node-gyp 编译
node-gyp build

# 启动 express 服务
node app.js

spice-html5 接入

SpiceLinkReply --> from_buffer

from_buffer: async function(a, at) {
    at = at || 0;

    let that = this;
    var url = 'https://127.0.0.1:18887/sm2-plugin/repair-pubKey'
    await $.ajax({

        success: function (data) {
            that.pub_key = data.pubKey;
        }
    })
    at = 4;
    at += Constants.SPICE_TICKET_PUBKEY_BYTES;

    var num_common_caps = dv.getUint32(at, true); at += 4;
    var num_channel_caps  = dv.getUint32(at, true); at += 4;
