Enabling Ethereum wallet encryption from the command line
The Ethereum wallet system is designed with security in mind, but sometimes it will be necessary to take extra precautions when storing private keys. One of the most effective ways to improve your wallet encryption is to use a command line tool to encrypt your existing wallets.
How to enable wallet encryption
To enable wallet encryption in Ethereum from the command line, you will need to use the “eth-wallet” and “eth-crypto-encrypt” tools. Here’s how to do it:
- Install the required packages:
sudo apt-get update
sudo apt-get install -y libethereumjs-rpc-dev libecryptos-dev
- Enable the Ethereum Development Repository (DVR):
- Run
dvr update' to download the latest DVR package:
DVR update
- Install the eth-wallet’ tool:
sudo apt-get install -y ethereum-tools
- Create a new encrypted wallet using the command line:
”awesome
eth wallet create –key-size 2048 –wallet-name MyWallet
- Set the key encryption method to AES-256-CBC:
eth wallet get-key — key name MyWallet — key size 2048 — encryption AES-256-CBC
“
Which command should I use?
To encrypt a previously unencrypted wallet from the command line, you can use:
- "eth-wallet create --encrypt AES-256-CBC" to generate and set the encryption pair keys.
- eth-wallet get-key – key name MyWallet – encryption AES-256-CBC` to retrieve an existing key pair.
Important Notes
When using wallet encryption, it is important to remember that you should never share your your private keys. If you need to transfer funds or manage your Ethereum account, be sure to use a secure exchange method and keep your private keys safe.
In short, enabling wallet encryption from the command line is an easy way to improve the security of your existing Ethereum wallets. By following these steps, you can set up encrypted key pairs and ensure that your private keys are protected from unauthorized access.
