This time I will bring younode.jsOperation soundVideofile encryption, node.js operation audio and video file encryptionNotesWhat are they? The following is a practical case. Let’s take a look.

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 };
