📌 模块概述
安全隐私功能保护用户的数据安全和隐私。包括密码保护、数据加密、隐私设置等功能。
🔗 完整流程
第一步:设置密码
用户可以设置应用密码来保护笔记。
第二步:验证密码
打开应用时需要输入密码。
第三步:加密数据
敏感数据被加密存储。
🔧 Web代码实现
javascript
async renderSecurity() {
return `
<div class="page active">
<div class="page-header">
<h1 class="page-title">🔒 安全隐私</h1>
</div>
<div class="security-settings">
<div class="form-group">
<label>设置密码</label>
<input type="password" id="new-password" placeholder="输入新密码" class="form-control">
<button class="btn btn-primary" onclick="app.setPassword()">设置</button>
</div>
<div class="form-group">
<label>隐私设置</label>
<label><input type="checkbox" id="encrypt-data"> 加密笔记数据</label>
<button class="btn btn-primary" onclick="app.savePrivacySettings()">保存</button>
</div>
</div>
</div>
`;
}
// 设置密码
async setPassword() {
try {
const password = document.getElementById('new-password').value;
if (!password || password.length < 6) {
Utils.showToast('密码长度至少6位', 'error');
return;
}
const hashedPassword = await this.hashPassword(password);
const settings = await noteDB.getSettings();
settings.password = hashedPassword;
await noteDB.updateSettings(settings);
Utils.showToast('密码已设置', 'success');
} catch (error) {
console.error('设置密码失败:', error);
Utils.showToast('操作失败,请重试', 'error');
}
}
// 密码哈希
async hashPassword(password) {
const encoder = new TextEncoder();
const data = encoder.encode(password);
const hashBuffer = await crypto.subtle.digest('SHA-256', data);
const hashArray = Array.from(new Uint8Array(hashBuffer));
return hashArray.map(b => b.toString(16).padStart(2, '0')).join('');
}
