如何在Cordova中保护localstorage和websql数据 - 离子应用

Question

存储在本地存储或WebSql数据库中的数据不受保护。 我们可以直接看到WebSql和本地存储的所有数据，因为它们以纯文本形式存储。

有什么办法保护数据？

Answer 1

是的，你可以用AES或其他算法加密/解密你的数据。也许你可以尝试实施https://github.com/digitalbazaar/forge#md5

// generate a random key and IV 
 
// Note: a key size of 16 bytes will use AES-128, 24 => AES-192, 32 => AES-256 
 
var key = forge.random.getBytesSync(16); 
 
var iv = forge.random.getBytesSync(16); 
 

 
/* alternatively, generate a password-based 16-byte key 
 
var salt = forge.random.getBytesSync(128); 
 
var key = forge.pkcs5.pbkdf2('password', salt, numIterations, 16); 
 
*/ 
 

 
// encrypt some bytes using CBC mode 
 
// (other modes include: CFB, OFB, CTR, and GCM) 
 
var cipher = forge.cipher.createCipher('AES-CBC', key); 
 
cipher.start({iv: iv}); 
 
cipher.update(forge.util.createBuffer(someBytes)); 
 
cipher.finish(); 
 
var encrypted = cipher.output; 
 
// outputs encrypted hex 
 
console.log(encrypted.toHex()); 
 

 
// decrypt some bytes using CBC mode 
 
// (other modes include: CFB, OFB, CTR, and GCM) 
 
var decipher = forge.cipher.createDecipher('AES-CBC', key); 
 
decipher.start({iv: iv}); 
 
decipher.update(encrypted); 
 
decipher.finish(); 
 
// outputs decrypted hex 
 
console.log(decipher.output.toHex());
