SQLCipher是一个开源的SQLite扩展,提供了AES-256位加密算法来加密SQLite数据库。这种方法无需修改SQLite的源代码,且实现相对简单。 安装SQLCipher 首先,你需要下载并编译SQLCipher库。这通常涉及解压源代码、配置编译选项,然后运行编译命令。 在代码中使用SQLCipher java String key = "yourEncryptionKey"; SQLiteDataSource...
(stderr, "Can't open database: %s\n", sqlite3_errmsg(db)); return 0; } rc = sqlite3_key(db, "your-encryption-key", strlen("your-encryption-key")); if (rc != SQLITE_OK) { fprintf(stderr, "Key error: %s\n", sqlite3_errmsg(db)); return 0; } // Perform other SQLite ...
IDEA(International Data Encryption Algorithm)国际数据加密算法,使用 128 位密钥提供非常强的安全性; RSA:由 RSA 公司发明,是一个支持变长密钥的公共密钥算法,需要加密的文件块的长度也是可变的,非对称算法; DSA(Digital Signature Algorithm):数字签名算法,是一种标准的 DSS(数字签名标准),严格来说不算加密算法; ...
SQLite3 Encryption API Functions #define SQLITE_HAS_CODEC #include <sqlite3.h> sqlite3_key, sqlite3_key_v2 Set the key for use with the database This routine should be called right after sqlite3_open. The sqlite3_key_v2 call performs the same way as sqlite3_key, but sets the encry...

导入命名空间:在C#代码文件的顶部,添加以下命名空间引用:using System.Data.SQLite; using System.Data.SQLite.EncryptionExtensions; 打开受密码保护的SQLite 3数据库:使用以下代码片段在C#中打开受密码保护的SQLite 3数据库:string connectionString = "Data Source=<database_file>;Password=<password>"; SQLite...
although they weren't officially announced. They were introduced on Feb 7, 2020:"Simplify the code by removing the unsupported and undocumented SQLITE_HAS_CODEC compile-time option". As a consequence, updating thewxSQLite3 encryption extensionto support SQLite version 3.32.0 and later was no long...
