我使用 sqlcipher.exe 执行
```base
sqlcipher.exe F:\testdata\xxx.db
sqlite> PRAGMA key = 'dd85344';
sqlite> PRAGMA cipher_use_hmac = off;
sqlite> PRAGMA cipher_page_size = 1024;
sqlite> PRAGMA kdf_iter = 4000;
sqlite> .table
```
成功了

这是我的 golang 代码
```golang
import (
"database/sql"
"fmt"
"testing"

_ "github.com/mutecomm/go-sqlcipher/v4"
)

func TestDecrypt(t *testing.T) {
dbname := fmt.Sprintf("%s?_pragma_key=%s&_pragma_cipher_use_hmac=off&_pragma_cipher_page_size=1024&_pragma_kdf_iter=4000", `F:\testdata\xxx.db`, "dd85344")
db, err := sql.Open("sqlite3", dbname)
if err != nil {
panic(err)
}
_, err = db.Query("SELECT id,value FROM userinfo")
if err != nil {
panic(err)
}
}
```
最后的 error 会报错 : "file is not a database"
