Load an Ed25519 Private Key from Hex

See more Ed25519 Examples

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

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

PowerShell

Add-Type -Path "C:\chilkat\ChilkatDotNet47-x64\ChilkatDotNet47.dll"

$success = $false

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

$privKey = New-Object Chilkat.PrivateKey

# 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 -eq $false) {
    $($privKey.LastErrorText)
    exit
}

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

# Let's get the public key to see that it computed the same value.
$sbPubKeyHex = New-Object Chilkat.StringBuilder
$privKeyHex = $privKey2.GetRawHex($sbPubKeyHex)
$("computed public key = " + $sbPubKeyHex.GetAsString())

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