This little script offers decryption and verification of the existing Ethereum wallets, as well as generation of a new wallet. You can use any utf-8 string as the password, which could provide with better security against the brute-force attack.
Use at your own risk.
- Decrypt the UTC JSON wallet and see the private key
- Run secp256k1 to make sure the private key is intact and really corresponds to the wallet address
- Generate a wallet
- pycrypto
- pysha3
- ecdsa
git clone https://github.com/Determinant/ethy.py
pip3 install --user ethy.py/
ethy.py --verify-key mywallet.json # unlock the wallet and verify whether the
# encrypted private key matches the address
ethy.py --show-key mywallet.json # reveal the private key (secp256k1)
ethy.py --gen > mywallet.json # generate a regular wallet (1s)
ethy.py --gen --light > mywallet.json # generate a wallet (fast)
ethy.py --gen --with-key > mywallet.json # generate a wallet with the given private key
