# Generate the private and public keys
openssl ecparam -name secp256k1 -genkey -noout | openssl ec -text -noout > key

# Extract the public key and remove the EC prefix 0x04
cat key | grep pub -A 5 | tail -n +2 | tr -d '\n[:space:]:' | sed 's/^04//' > pub

# Extract the private key and remove the leading zero byte
cat key | grep priv -A 3 | tail -n +2 | tr -d '\n[:space:]:' | sed 's/^00//' > priv

# Generate the hash and take the address part
