Generating Ethereum accounts in Javascript Generating randomness. In the main.js file include the bip39 package. Generate a Public / Private Keypair. Using this mnemonic as a source of randomness. Derive the Address. Deriving an Ethereum address from a public key requires an additional. 2019-1-19 A private key represented as random words is safe. For a brute-force attacker such a private key is just as difficult to guess as the fully random 64 character bitcoin private key. Also, words are much easier to write down or even remember. Generating Whisper Key Pair In whisper, messages have to be encrypted with either a symmetric or an asymmetric key to prevent them from being read by anyone other than the intended recipient. After you've connected to the whisper client you'll need to call the client's NewKeyPair method to generate a new public and private pair that the node will manage.
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.

Importing private key to geth

You can use the generated private key to import in to geth (https://github.com/ethereum/go-ethereum).
Note that geth will ask you immediately to choose a passphrase to protect the newly imported key.
