Windows Phone 开发：数据加密、图像与媒体处理全解析

1. 数据加密与存储

在开发过程中，数据的加密与安全存储至关重要。以下代码展示了如何从存储中获取加密的密码和盐值，并进行解密操作：

if (settings.Contains("Password")) { byte[] encryptedPasswordBytes = (byte[])settings["Password"]; byte[] decryptedPasswordBytes = ProtectedData.Unprotect(encryptedPasswordBytes, null); Password = Encoding.UTF8.GetString(decryptedPasswordBytes, 0, decryptedPasswordBytes.Length); } if (settings.Contains("Salt")) { byte[] encryptedSaltBytes = (byte[])settings["Salt"]; byte[] decryptedSaltBytes = ProtectedData.Unprotect(encryptedSaltBytes, null); Salt = Encoding.UTF8.GetString(decryptedSaltBytes, 0, decryptedSaltBytes.Length); } if (Password != String.Empty) SavePasswordAndSalt = true;
