废话不多说了，直接给大家贴代码了，具体代码如下所示：
fs.readFile('./downsuccess/'+name+'', {flag: 'r+', encoding: ''}, function (err, data) {
console.log('读取中')
if(err) {
return;
}
let b = new Buffer(data);
let c = b.toString('hex');
let cipherBuffer = _this.cipher(data);
fs.writeFile('./downsuccess/'+name+'',cipherBuffer,[],function(){
console.log(`${name}加密完成`);
_this.downAll(_this.downList,_this.downCall)
})
});
export function cipher (buf) {
var encrypted = "";
var cip = crypto.createCipher('rc4', '密匙');
encrypted += cip.update(buf, 'hex', 'hex');
encrypted += cip.final('hex');
return encrypted
};
