testing the contents of the portfolio.dat file with SQLITE3

When it comes to storing and managing private keys in the blockchain, such as Ethereum, wallets usually use the “.d” file called “wallet.dat”. This file is used to store data on the state of the portfolio, including the public key and private keys. In this article, we will examine how to examine the contents of the “wallet.dat” file using SQLite3.

What’s in the wallet file?

As Andrew Chow said in 2017, when the database was still very good (Berkeley DB), but not SQLite, the “wallet.dat” file contains your private keys, public keys and other confidential information. However, in 2020, Ethereum went to use SQLITE3 as a default database that provides a safer and efficient way of storing the portfolio data.

testing the contents of the portfolio.dat file with SQLITE3

To examine the contents of the Palllet.dat using SQLITE3, you can follow these steps:

1.

`sql

SQLITE3 PIELONA.DB

• Load portfolio data : Load data from the “wallet.dat” file to the variable or table using the following query:

`sql

Select * from the wallet;

This will display all columns and poems in the “Wallet” table in which you can find private keys, public keys and other confidential information.

• Access to specific data : If you need access to specific data in the “Portier.dat” file, you can use different methods, such as:

* Recovery of a single value

: Use the following query:

`sql

Choose * from the wallet where ID = 123; - replace the desired identifier

This will recover a specific line or column from the “Wallet” Wallet “table based on the given identifier.

* Access to many values ​​: To access many values, use the “in” operator (SQLITE3 does not support it directly. Instead, you can use the “Attach” clause):

`sql

Choose * from the wallet where ID W (123, 456);

This will recover all rows in which the identified column fits one of the specific identifiers.

• Error handling : Always remember to properly handle errors when working with SQLITE3, because it is a non -transitional database that may fail if an error occurs during the query.

Application

Studying the contents of the “portfolio.dat” file using SQLITE3 provides valuable information about the portfolio state and enables efficient data search. By following these steps, you can unlock the secrets of the Ethereum portfolio and gain control over private keys. Remember to always be careful when handling sensitive information and make sure that your database is properly protected to protect against potential threats.

Examples of use

Suppose you have the Palllet.dat file with the following content:

`Markdown

ID secret_key

----- | --------------

1234 | my_secret_key

4567 | other_secret_key

You can use SQLITE3 to load and access this data, as:

`sql

- load the portfolio data into the table

Select * from the wallet;

- access to specific data (downloading a single poem from ID 1234)

Choose * from the wallet where ID = 1234;

- Get access to many values ​​(downloading all poems in which the ID fits up to 1234 or 4567)

Choose * from the wallet where ID W (1234, 4567);
