The light ethereum wallet is a compact ethereum wallet generator that creates single private-public-key pairs to derive a single ethereum address.
NOTE: This wallet DOES NOT SUPPORT BIP39 mnemonics which can control and derive entire crypto vaults with up to 2 billion addresses (using BIP32) per cryptocurrency and with support for multiple cryptocurrency accounts (using BIP44). For BIP39 tools, see this repository. In addition, this wallet may not be compatible with many cryptocurrency wallets that do not support the importing of private keys in plain text format.
The elliptic curve-related tools are used from the official eth-keys library which belongs to the Ethereum Foundation and listed here on Github on the Ethereum repository and can be installed via the commamnd line on a Mac via the terminal.app using pip install eth-keys.
The pysha3 libarary contains the Keccak 256 hashing algorithm using in Ethereum and in the address foramtting stpes and can be found on the PyPi website (and on Github unwrapped) or installed via the commamnd line on a Mac via the terminal.app using pip install pysha3.
The secrets library is used to source 256 bits of entropy and fed into Python's cryptographically-secure pseudo-random number generator (CSPRNG) which is generates the private key (from which all subsequent steps are derived). See this article for more on Python's secrets library.
The eth-keys libary contains a suite of commands available via api, read more here from their Readme.md file.
The following is an example of what the light-ethereum-wallet.py file from this repository will print when opened with Python as an exectuable (the values below should never be used on mainnet):
