作为一名鸿蒙开发者,我深知应用安全的重要性。鸿蒙OS提供了全方位的安全防护机制,让我们能够轻松构建安全可靠的应用程序。今天就来分享几个关键的安全开发实践。
以下是一个完整的鸿蒙安全实践示例,包含权限申请、数据加密和安全通信:
import abilityAccessCtrl from '@ohos.abilityAccessCtrl';
import cryptoFramework from '@ohos.cryptoFramework';
import http from '@ohos.net.http';
import preferences from '@ohos.data.preferences';
// 1. 动态权限申请
async function requestPermissions() {
let atManager = abilityAccessCtrl.createAtManager();
try {
await atManager.requestPermissionsFromUser(
['ohos.permission.INTERNET', 'ohos.permission.READ_MEDIA']
);
} catch (err) {
console.error(`权限申请失败: ${err.code}, ${err.message}`);
}
}
// 2. 数据加密存储
async function secureDataStorage() {
let context = getContext(this) as common.UIAbilityContext;
let pref = await preferences.getPreferences(context, 'secureData');
// AES加密
let cipher = await cryptoFramework.createCipher('AES256|ECB|PKCS7');
let key = await cryptoFramework.createSymKeyGenerator('AES256').convertKey({
data: new Uint8Array(32).fill(0x11)
});
await cipher.init(cryptoFramework.CryptoMode.ENCRYPT_MODE, key, null);
let plainText = '敏感数据';
let encrypted = await cipher.doFinal({ data: new Uint8Array(plainText.split('').map(c => c.charCodeAt(0))) });
await pref.put('encryptedData', encrypted.data);
await pref.flush();
}
// 3. 安全网络通信
async function secureNetworkRequest() {
let httpRequest = http.createHttp();
await httpRequest.request(
"https://api.secure.com/data",
{
method: 'GET',
extraData: {
caPath: '/resources/rawfile/cert.pem', // 自定义CA证书
cipherSuites: 'TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256' // 指定加密套件
}
}
);
}
鸿蒙的安全体系为开发者提供了强大的武器库,但安全不仅是技术问题,更是一种开发理念。只有将安全意识融入开发全流程,才能真正构建出值得用户信赖的应用。记住:在安全领域,预防永远比修复更重要!
