Frequently Asked Questions
Is my data safe?
Yes. All processing happens entirely in your browser. Your data never leaves your device and is never uploaded to any server.
How is the address derived?
The private key is multiplied on the secp256k1 curve to get the public key. The public key is hashed with keccak-256, and the last 20 bytes become the Ethereum address, formatted with an EIP-55 checksum.
Can I use these keys with MetaMask?
Yes. You can import the private key into MetaMask or any Ethereum wallet. However, for real funds, consider generating keys on an offline device.
