I wrote a guide previously about how to access your private keys from your Android wallet, but times have moved on and it’s due for an update.
This guide leverages a python script created by jleni to make the process super easy.
You should already be backing up your keys and know how to do this!
But for completeness, here’s how:
Open the app.
If you have a spending PIN on your account, you must remove it before continuing. This retrieval approach does not decrypt private keys that are encrypted with a spending PIN.
option menu and select
Back up wallet.
Give your wallet a good password. And I mean really good. If someone gets this back up, they have all your coins.
Download the script.
git clone https://github.com/jleni/wallet-decrypt.git cd wallet-decrypt
Download and install
python (preferably Python 3) from the Python website.
Download and install
pip from the pip website.
Install the python dependencies.
sudo pip install pycryptodome sudo pip install protobuf
The script requires your password be entered into the command line. This is poor security practice.
I recommend altering the script to contain your password instead of using the argument and then erase the script afterwards.
args.password with your password in the following line:
w = get_wallet(args.filename, args.password)
Don’t forget to delete / restore the script after use.
A BIP-39 mnemonic is generated by the script for each address. This is essentially a human friendly version of your private key.
Keep in mind that the mnemonic can be used to derive your private key so must be handled as securely as you would for your private key.
Read that above line again! This is important.
Run your script against the file to obtain your mnemonic.
python wallet-decrypt.py <your_backup_file> <your_backup_password>
<your_backup_file> is the filename and
<your_backup_password> is the file password. If you replaced the password in the Optional Security step earlier, you can use anything in place of the password argument.
The script will output the mnemonic. Be sure to keep this in a safe place.
