网络安全入侵者是指那些利用漏洞或其他手段,擅自进入计算机或网络系统,从而获取或破坏计算机或网络系统的信息的人。他们通常是黑客或骇客。
附上一个简单的加密示例代码:
const crypto = require('crypto');
const algorithm = 'aes-256-cbc';
const key = crypto.randomBytes(32);
const iv = crypto.randomBytes(16);
function encrypt(text) {
let cipher = crypto.createCipheriv(algorithm, Buffer.from(key), iv);
let encrypted = cipher.update(text);
encrypted = Buffer.concat([encrypted, cipher.final()]);
return { iv: iv.toString('hex'), encryptedData: encrypted.toString('hex') };
}
function decrypt(iv, encryptedData) {
let decipher = crypto.createDecipheriv(algorithm, Buffer.from(key), Buffer.from(iv, 'hex'));
let decrypted = decipher.update(Buffer.from(encryptedData, 'hex'));
decrypted = Buffer.concat([decrypted, decipher.final()]);
return decrypted.toString();
}
let encryptedData = encrypt('这是一条需要加密的数据').encryptedData;
let iv = encrypt('这是一条需要加密的数据').iv;
console.log(decrypt(iv, encryptedData));
以上代码使用Node.js的crypto
模块进行AES-256-CBC加密和解密,保障数据安全传输。
