Checking the contents of the Most File using SQLITE3
When it comes to storing and managing private keys in a blockchain network, such as Ethereum, the wallets usually use “.datfile called" Wallet.dat ". This file is used to save data on wallet, including its public key and private keys. In this article, we will study how to check the content of the "Wallet.dat" file using SQLITE3.
What is a file Wallet.dat?
As Andrew Chow said in 2017, when the database was still BDB (Berkeley DB), but not SQLITE, the "Wallet.dat" file is your private keys, public keys and other sensitive information. However, in the year 2020, Ethereum switched to the use of SQLITE3 as a default database that provides a more secure and more efficient way to store your wallet data.
Checking the contents of the Most File using SQLITE3
To check the content of the "Wallet.dat" file using SQLITE3, you can take the following:
- Join the database : First, connect to your SQLITE3 database by fulfilling the following query:
Sql
Sqlite3 wallet.db
`
- Load wallet data : load data from the “Wallet.dat” file in a variable or table using the following query:
`Sql
Select * from wallet;
`
It will show all the columns and rows in the table, where you can find your private keys, public keys and other sensitive information.

Access to specific data
: If you need access to specific data in the “Wallet.dat” file, you can use different methods such as:
* Getting one Value : Use the following query:
`Sql
Select * from the wallet where id = 123; – Replace with preferred ID
`
This will regain a particular row or column from the table “Wallet” based on the ID.
* When accessing multiple values : Use the operator `sqlite3 not directly supported to access multiple values. Instead, you can use the “Join” clause):
Sql
Select * from wallet where ID (123, 456);
`
It will get all the rows in which the ID column matches each of the specified id.
- Error Treatment : Always remember that when working with SQLITE3, you always do the right mistakes as it is a non -producing database that may fail when an error occurs.
Conclusion
By checking the content of the “Wallet.dat” file using SQLITE3 gives you a valuable insight into your wallet and allows you to get data obtained effectively. By doing these steps, you can unlock your Ethereum wallet secrets and gain control over private keys. Remember to always use caution when processing sensitive information and make sure your database is properly secured to protect against potential threats.
Example of use of use
Let’s say you have a file “Wallet.datwith the following content:
Markdown
ID Secret_key
—- | ————-
1234 my_secret_key
4567 another_secret_key
`
You can use SQLITE3 to load and access these data such as:
`Sql
– Load your wallet data in the table
Select * from wallet;
– Access specific data (getting one row with ID 1234)
Select * from the wallet where id = 1234;
– Access multiple values (getting all rows where ID coincides with 1234 or 4567)
Select * from the wallet where ID in (1234, 4567);
