Lua Requires Chilkat v9.5.0.83+

Load an Ed25519 Private Key from Hex

See more Ed25519 Examples

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

local chilkat = require("chilkat")

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

local privKey = chilkat.PrivateKey.new()

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

-- Load these values into the Chilkat private key object:
local success = privKey:load_ed25519(privKeyHex, pubKeyHex)
if not success then
    print(privKey.last_error_text)
    return
end

-- ---------------------------------------------------------------
-- We don't actually need the public key.  If we pass an empty string for the public key,
-- Chilkat will automatically compute it.
local privKey2 = chilkat.PrivateKey.new()
success = privKey2:load_ed25519(privKeyHex, "")

-- Let's get the public key to see that it computed the same value.
local sbPubKeyHex = chilkat.StringBuilder.new()
privKeyHex = privKey2:get_raw_hex(sbPubKeyHex)
print("computed public key = " .. sbPubKeyHex:get_as_string())

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