Request: Generate keypair for usage in e.g. BigChainDB (doc pub key gen) about elliptic-php HOT 3 CLOSED

This is low level library which provides general algorithms with operating on different kinds of elliptic curves. On of it is ed25519 which is used in BigChainDB. The algorithms used to encode keys / generate them in some way from given seed that are specific for software using those keys are of course not in scope of this library. As I see BigChainDB uses Base58 encoded private and public keys so below I put you an example how you can generate a pair of such keys using mnemonic seed (I did not check if it works with BigChainDB thought): use Elliptic\EdDSA;use StephenHill\Base58;$mnemonic = "scheme spot photo card baby mountain device kick cradle pact join borrow";$secret = hash_pbkdf2('sha512', $mnemonic, 'mnemonic', 2048);$ec = new EdDSA('ed25519');$kp = $ec->keyFromSecret($secret);assert($secret == $kp->getSecret('hex'));echo "Secret: " . $kp->getSecret('hex') . PHP_EOL;echo "Private: " . $kp->priv()->toString('hex') . PHP_EOL;echo "Public: " . $kp->getPublic('hex') . PHP_EOL;$b58 = new Base58();echo PHP_EOL;echo "B58 Private: " . $b58->encode(hex2bin($kp->priv()->toString('hex'))) . PHP_EOL;echo "B58 Public: " . $b58->encode(hex2bin($kp->getPublic('hex'))) . PHP_EOL; Let me know if it helps. — You are receiving this because you authored the thread.
