# Ethereum wallet generator
Simple script collection, currently in bash and python format, to generate a complete offline Ethereum wallet by creating an ECDSA keypair and derive its Ethereum address.
You can read my article about it here: https://kobl.one/blog/create-full-ethereum-keypair-and-address/
**IMPORTANT** The python version of this script has been updated to support mixed-case checksum address encoding through [EIP55](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-55.md).
## Python dependencies
- ECDSA https://pypi.python.org/pypi/ecdsa
- pysha3 https://pypi.python.org/pypi/pysha3
You can also use the included requirements.txt file to install them
```bash
pip install -r requirements.txt
```
## Bash dependencies
- OpenSSL
- SHA3sum (keccak-256sum) https://github.com/maandree/sha3sum
*Compiled, statically linked versions of the keccak-256sum executable are available in the lib folder of this repo for i386 and x86_64.*
## Importing private key to geth
You can use the generated private key to import in to geth (https://github.com/ethereum/go-ethereum).
```bash
# First save the private hexadecimal key to a file
echo eff415edb6331f4f67bdb7f1ecc639da9bcc0550b100bb275c7b5b21ce3a7804 > key
# Then use account import feature of geth (here importing in the 'testnet' directory)
./go-ethereum/build/bin/geth --datadir ~/.ethereum/testnet account import key
```
Note that geth will ask you immediately to choose a passphrase to protect the newly imported key.
## Example
```bash
./ethereum-wallet-generator.py
