使用JavaScript Crypto API实现AES加密和解密,并将加密后的密码通过Ajax请求发送到后端进行解密。
以下是实现代码示例:
1.在前端JavaScript中,使用Crypto API实现AES加密和解密:
const KEY = 'my secret key'; // 密钥
const IV = 'some initialization vector'; // 初始向量
function encryptPassword(password) {
const passwordBytes = new TextEncoder().encode(password); // 将字符串转换为字节数组
const ivBytes = new TextEncoder().encode(IV); // 将初始向量字符串转换为字节数组
const keyBytes = new TextEncoder().encode(KEY); // 将密钥字符串转换为字节数组
return crypto.subtle.importKey('raw', keyBytes, { name: 'AES-CBC' }, false, ['encrypt'])
.then(key => crypto.subtle.encrypt({ name: 'AES-CBC', iv: ivBytes }, key, passwordBytes))
.then(encryptedBytes => new Uint8Array(encryptedBytes))
.then(encryptedBytes => Array.from(encryptedBytes).map(byte => String.fromCharCode(byte)).join(''))
.catch(error => console.error(error));
}
function decryptPassword(encryptedPassword) {
const ivBytes = new TextEncoder().encode(IV); // 将初始向量字符串转换为字节数组
const keyBytes = new TextEncoder().encode(KEY); // 将密钥字符串转换为字节数组
const encryptedBytes = encryptedPassword.split('').map(char => char.charCodeAt(0)); // 将加密后的密码字符串转换为字节数组
return crypto.subtle.importKey('raw', keyBytes, { name: 'AES-CBC' }, false, ['decrypt'])
.then(key => crypto.subtle.decrypt({ name: 'AES-CBC', iv: ivBytes }, key, new Uint8Array(encryptedBytes)))
.then(decryptedBytes => String.fromCharCode(...new Uint8Array(decryptedBytes)))
.catch(error => console.error(error));
}
2.在前端JavaScript中,通过Ajax请求将加密后的密码发送到后端进行解密:
function transferPassword(password) {
encryptPassword(password).then(encryptedPassword => {
$.ajax({
url: '/transfer-password',
type: 'POST',
data: { password: encryptedPassword },
success: response => {
if (response.success) {
// 密码成功传输到后端并已解密
} else {
//
