Running a wallet.dat Extraction Script on Termux (Android)

This content explains the practical execution context of running the provided Python script on Termux (Android). It focuses on file placement, required Termux configuration, and execution prerequisites so the script can run successfully without missing any necessary action. The Python code itself is included exactly as provided.

Termux Environment Preparation

Termux must be installed from a trusted source (F-Droid is recommended). After installation, the environment needs basic package initialization and Python support.

Python’s package manager is required to install external libraries used by the script.

Installing Required Python Libraries

The script depends on cryptographic, encoding, and networking libraries that are not bundled by default.

File System Access in Termux

To allow Termux to read files from Android storage (internal storage or SD card), storage permission must be enabled once:

This command creates a symbolic link at:

This directory maps to the device’s internal storage.

Placing wallet.dat

The script expects wallet.dat to be readable from the current working directory. A common and reliable approach is:

- Copy wallet.dat into Android internal storage (e.g. Download folder)

- Move it into Termux’s home directory

After this, both the Python script and wallet.dat should reside in the same directory:

Execution Context in Termux

The script must be executed from the directory containing both:

- the Python file (for example: extract.py)

- wallet.dat

Run using:

During execution, Termux will generate:

- keys.txt containing extracted WIF keys

- saldo.txt containing derived addresses and balances

Important Execution Notes

- Termux does not require root access for this process

- The script relies on outbound HTTPS access

- File permissions must allow read access to wallet.dat

- All files are processed locally except balance queries

This ensures the script can be executed on Android via Termux without missing any operational requirement.
