Navicat's method to view SQLite database password

Summary: Navicat cannot view SQLite passwords because: SQLite does not have traditional password fields. SQLite's security relies on file system permission control. If the file password is forgotten, it cannot be retrieved (unless the database is encrypted, the key is required).

Navicat peeks into SQLite passwords? Let's wait!

Many friends want to use Navicat to view the password of SQLite database, and this idea itself is a bit... We have to figure out first that the password mechanism of SQLite is completely different from those large databases (MySQL, PostgreSQL, etc.). It does not have an independent "password" field at all, and the way of storing passwords is even more... Well, how to say it, it is more "simple". So, do you use Navicat to find the password directly? There is basically no chance. This article will talk in depth about why and some more reliable ideas.

Let’s first talk about SQLite’s “password” mechanism, or its security policy. The security of SQLite mainly depends on the permission control of the file system. If you limit the read and write permissions of the database file (.db), it is equivalent to adding a lock to the database. This is completely different from traditional database login verification with username and password. Tools like Navicat are good at handling databases with independent username and password systems, and they seem a little overwhelmed with "alternative" such as SQLite.

You might ask, what if I forget the password to access the database file (or, forget to set file permissions)? This is the key. If your database file is not encrypted, then, sorry, you can hardly get back the "password" because there is no password to get back. What you need to consider is how to regain access to the file, depending on your operating system and file permission settings. For example, in Linux systems, you can use the chmod command to modify file permissions.

If your database file is encrypted (for example, through the SQLCipher library), the situation is a little more complicated. At this time, you need to know the encrypted key to decrypt the database file. And this key is what you really need to retrieve. If you forget the key, then... it will basically be cold. There is no shortcut, you can only consider restoring the backup or rebuilding the database.

Let's look at a simple example, suppose you have an unencrypted SQLite database file mydatabase.db and you want to open it with Navicat. You might try to enter your password in Navicat, but in reality, Navicat doesn't send any password verification requests to SQLite because it doesn't need it at all. You just need to make sure Navicat has permission to access mydatabase.db file. If file permissions do not allow access, Navicat will prompt you that there is no permission.

So, instead of searching for non-existent passwords in Navicat, it is better to check the file permissions first to see if it is inaccessible due to permission issues. If SQLCipher is used, then remember your encryption key honestly. Remember, safety first, and developing good password management habits is much more important than post-remediation.

Finally, I would like to remind everyone that database security issues should be taken seriously. Don't rely on some unreliable methods, but do a good job of security planning from the beginning, choose the right database encryption solution, and keep your keys properly. This is the truly effective safety measure.
