Demonstrates how to get the public key in base64 format from a private key. Lua

local chilkat = require("chilkat")

-- Load a private key from base64.
local bd = chilkat.BinData.new()
local success = bd:append_encoded("MHQCA....n0Q==", "base64")

local privKey = chilkat.PrivateKey.new()
success = privKey:load_any_format(bd, "")
if not success then
    print(privKey.last_error_text)
    return
end

local pubKey = chilkat.PublicKey.new()
privKey:to_public_key(pubKey)

local pubKeyBase64 = pubKey:get_encoded(true, "base64")
print(pubKeyBase64)
