(Ruby) Load an Ed25519 Private Key from Hex

Demonstrates how to load an Ed25519 private key from raw hex bytes.

Note: This example requires Chilkat v9.5.0.83 or greater.

Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

require 'chilkat'

# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

privKey = Chilkat::CkPrivateKey.new()

# We have the hexidecimal encoded bytes of the private key and public key:
privKeyHex = "d4ee72dbf913584ad5b6d8f1f769f8ad3afe7c28cbf1d4fbe097a88f44755842"
pubKeyHex = "19bf44096984cdfe8541bac167dc3b96c85086aa30b6b6cb0c5c38ad703166e1"

# Load these values into the Chilkat private key object:
success = privKey.LoadEd25519(privKeyHex,pubKeyHex)
if (success == false)
    print privKey.lastErrorText() + "\n";
    exit
end

# ---------------------------------------------------------------
# We don't actually need the public key.  If we pass an empty string for the public key,
# Chilkat will automatically compute it.
privKey2 = Chilkat::CkPrivateKey.new()
success = privKey2.LoadEd25519(privKeyHex,"")

# Let's get the public key to see that it computed the same value.
sbPubKeyHex = Chilkat::CkStringBuilder.new()
privKeyHex = privKey2.getRawHex(sbPubKeyHex)
print "computed public key = " + sbPubKeyHex.getAsString() + "\n";

# The output should be:
# computed public key = 19bf44096984cdfe8541bac167dc3b96c85086aa30b6b6cb0c5c38ad703166e1
