node加密rdp的密码

1. 代码

代码参考: https://github.com/node-ffi/node-ffi/issues/355

const fs = require('fs'); 
const ref = require('ref');
const ffi = require('ffi');
const Struct = require('ref-struct')
const Array = require('ref-array')
const DATA_BLOB = Struct({
    cbData: ref.types.uint32,
    pbData: 'string' // ref.refType(ref.types.byte)
})
const PDATA_BLOB = new ref.refType(DATA_BLOB)
const Crypto = new ffi.Library('Crypt32', {
    'CryptUnprotectData': ['bool', [PDATA_BLOB, 'string', 'string', 'void *', 'string', 'int', PDATA_BLOB]],
});
const data_blob_input = new DATA_BLOB();
data_blob_input.cbData = row.encrypted_value.length;
data_blob_input.pbData = row.encrypted_value;
const data_blob_output = new DATA_BLOB();
const result = Crypto.CryptUnprotectData(data_blob_input.ref(), null, null, null, null, 0, data_blob_output.ref());
cookies[row.name] = data_blob_output.pbData.slice(0, data_blob_output.cbData);
console.log(row.name, cookies[row.name])

2. ffi安装

Node 10 and lower
    npm i ffi
    https://www.npmjs.com/package/ffi
    https://github.com/node-ffi/node-ffi
Node 11 and 12
    npm i @saleae/ffi
    https://www.npmjs.com/package/@saleae/ffi
    https://github.com/lxe/node-ffi/tree/node-12
Node 13 and higher
    npm i ffi-napi
    https://www.npmjs.com/package/ffi-napi
    https://github.com/node-ffi-napi/node-ffi-napi

2.1 安装ffi注意事项

1. 需要python2环境

2. MSBUILD : error MSB3428: 未能加载 Visual C++ 组件“VCBuild.exe”

   解决: 管理员身份启动cmd运行: npm install --global --production windows-build-tools
