用加密sqlite 使用了 sqlciphone

1、在nuget中安装 （1）microsoft.entityframeworkcore.sqlite.core  （2）sqlitepclraw.bundle_e_sqlcipher

2、设置连接字符串 在appsettings.json 里 

"ConnectionStrings": {
　　"SqliteConnection": "Filename=t1.db"
}

3、在program.cs里

var sqliteBaseConnectionString = builder.Configuration.GetConnectionString("SqliteConnection") ?? throw new InvalidOperationException("Connection string 'SqliteConnection' not found.");
var sqliteConnectionString = new SqliteConnectionStringBuilder(sqliteBaseConnectionString)
{
　　Mode = SqliteOpenMode.ReadWriteCreate,
　　Password = "123456",

　　//DataSource = "resource/t1.db",
}.ToString();

builder.Services.AddDbContext<SqliteDbContext>(options =>
options.UseSqlite(sqliteConnectionString));

使用SQLiteStudio(3.4.3) 连接加密数据库

1、选择数据库类型  SQLCipher

2、文件：先择相应的数据库文件

3、密码：填入123456 （上面程序设置的密码）

4、加密算法配置（SQCipher 4）：

PRAGMA kdf_iter = '256000';

PRAGMA cipher_page_size = 4096;

PRAGMA cipher_hmac_algorithm = HMAC_SHA512;

PRAGMA cipher_default_kdf_algorithm = PBKDF2_HMAC_SHA512;

---------------------------------------------------------------------------------------------------

下载 DB Browser for SQLite: http://www.sqlitebrowser.org/dl/

使用 DB Browser （SQLCipher） 查看加密数据库

1、输入密码

2、SQLCipher 4 默认
