See more Ed25519 Examples

Demonstrates how to get the private and public key parts of an Ed25519 key in lowercase hex formmat.

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

integer li_rc
integer li_Success
oleobject loo_PrivKey
oleobject loo_SbPubKeyHex
string ls_PrivKeyHex

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

// Load an Ed25519 key from some format..
loo_PrivKey = create oleobject
li_rc = loo_PrivKey.ConnectToNewObject("Chilkat.PrivateKey")
if li_rc < 0 then
    destroy loo_PrivKey
    MessageBox("Error","Connecting to COM object failed")
    return
end if

// This loads an Ed25519 key from an unencrypted PEM file (no password required).
li_Success = loo_PrivKey.LoadAnyFormatFile("qa_data/eddsa/ed25519.pem","")
if li_Success = 0 then
    Write-Debug loo_PrivKey.LastErrorText
    destroy loo_PrivKey
    return
end if

// The key type should be "ed25519" to indicate an Ed25519 key.
Write-Debug "key type = " + loo_PrivKey.KeyType

// What is the size of the private key in bits?  (should always be 256 bits for Ed25519)
Write-Debug "size in bits = " + string(loo_PrivKey.BitLength)

// Get the private and public key parts in raw hex format:
loo_SbPubKeyHex = create oleobject
li_rc = loo_SbPubKeyHex.ConnectToNewObject("Chilkat.StringBuilder")

ls_PrivKeyHex = loo_PrivKey.GetRawHex(loo_SbPubKeyHex)

// We should have a 32-byte private key (a 64 character hex string).
Write-Debug "private key = " + ls_PrivKeyHex

// We should have a 32-byte public key (a 64 character hex string).
Write-Debug "public key = " + loo_SbPubKeyHex.GetAsString()

// Sample output:
// key type = ed25519
// size in bits = 256
// private key = d4ee72dbf913584ad5b6d8f1f769f8ad3afe7c28cbf1d4fbe097a88f44755842
// public key = 19bf44096984cdfe8541bac167dc3b96c85086aa30b6b6cb0c5c38ad703166e1
