Ruby で Ethereum の秘密鍵・アドレスを生成

code:example.rb

require 'openssl'

require 'base16'

require 'digest/sha3'

def eth_address(public_key)

s = public_key2, 128

s.downcase!

s = Base16.decode16(s)

h = Digest::SHA3.hexdigest(s, 256)

a = '0x' + h-40..-1

return a

end

ec = OpenSSL::PKey::EC.new('secp256k1')

ec.generate_key

public_key = ec.public_key.to_bn.to_s(16)

private_key = ec.private_key.to_s(16)

eth_address = eth_address(public_key)

puts "address: #{eth_address}"

puts "private_key: #{private_key}"
