javascript怎樣利用C#生成的RSA公鑰對字符串加密？

js對公鑰串進行加密的寫法：

依賴：RSA.js BigInt.js 和Barrett.js

如何從一個nodejs子進程的CWD

1.啟動子與父目錄的CWD：

var exec = require(‘child_process’).exec;

var path = require(‘path’)

var parentDir = path.resolve(process.cwd(), ‘..’);

exec(‘doSomethingThere’, {cwd: parentDir}, function (error, stdout, stderr) {

// if you also want to change current process working directory:

process.chdir(parentDir);

});

更新：如果你想找回子的CWD：

var fs = require(‘fs’);

var os = require(‘os’);

var exec = require(‘child_process’).exec;

function getCWD(pid, callback) {

switch (os.type()) {

case ‘Linux’:

fs.readlink(‘/proc/’ + pid + ‘/cwd’, callback); break;

case ‘Darwin’:

exec(‘lsof -a -d cwd -p ‘ + pid + ‘ | tail -1 | awk \'{print $9}\”, callback);

break;

default:

callback(‘unsupported OS’);

}

}

// start your child process

// note that you can’t do like this, as you launch shell process

// and shell’s child don’t change it’s cwd:

// var child1 = exec(‘cd .. sleep 1 cd .. sleep 1’);

var child1 = exec(‘some process that changes cwd using chdir syscall’);

// watch it changing cwd:

var i = setInterval(getCWD.bind(null, child1.pid, console.log), 100);

child1.on(‘exit’, clearInterval.bind(null, i));

2.

如果你想獲得當前的工作目錄，而不訴諸操作系統行實用程序，你的「作戰測試」shelljs庫，這些抽象的東西給你，而子進程。

var sh = require(“shelljs”);

var cwd = sh.pwd();

有你有它的變量CWD握着你的當前工作目錄，無論你在Linux，Windows CodeGo.net，或FreeBSD。

3.

只是一個想法，如果你知道子進程的PID，並pwdx安裝（有可能在Linux上），你可以從一個節點得到子的CWD執行。
