SQLCipher使用256位AES加密来保护数据库文件。 2. 确定适用的解密工具和库 对于使用SQLCipher加密的SQLite数据库,可以使用SQLCipher库进行解密。SQLCipher提供了与SQLite类似的API,但增加了加密和解密功能。 3. 准备加密的SQLite数据库文件 确保你有一个使用SQLCipher加密的SQLite数据库文件。这个文件在没有正确解密的情况下...

1. 首先,我们需要创建一个用于加密和解密的工具类,如下所示: import javax.crypto.Cipher; import javax.crypto.spec.SecretKeySpec; import android.util.Base64; public class AESUtil { private static final String ALGORITHM = "AES"; private static final String TRANSFORMATION = "AES/ECB/PKCS5Padding"; ...
I’m trusting experts for that opinion). AES supports three different key sizes, 128, 192, and 256 (the larger the key, the more secure the encryption and the more processing power it takes toencryptor decrypt). Apple uses AES-128 and AES-256 in several places in Mac OS X, including ...

AES-256 is reliable. Beside that SQLiteCrypt only decrypts one block (page) at time, so even memory dump is useless for hackers It just works SQLiteCrypt works everywhere SQLite works. Just rebuild and replace SQLite runtime and add 2 PRAGMA ...
