(Unicode C) Get an Ed25519 Key in Raw Hex Format

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.

void ChilkatSample(void)
    {

    BOOL success;

    // 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..
    privKey = CkPrivateKeyW_Create();

    // This loads an Ed25519 key from an unencrypted PEM file (no password required).
    success = CkPrivateKeyW_LoadAnyFormatFile(privKey,L"qa_data/eddsa/ed25519.pem",L"");
    if (success == FALSE) {
        wprintf(L"%s\n",CkPrivateKeyW_lastErrorText(privKey));
        CkPrivateKeyW_Dispose(privKey);
        return;
    }

    // The key type should be "ed25519" to indicate an Ed25519 key.
    wprintf(L"key type = %s\n",CkPrivateKeyW_keyType(privKey));

    // What is the size of the private key in bits?  (should always be 256 bits for Ed25519)
    wprintf(L"size in bits = %d\n",CkPrivateKeyW_getBitLength(privKey));

    // Get the private and public key parts in raw hex format:
    sbPubKeyHex = CkStringBuilderW_Create();
    privKeyHex = CkPrivateKeyW_getRawHex(privKey,sbPubKeyHex);

    // We should have a 32-byte private key (a 64 character hex string).
    wprintf(L"private key = %s\n",privKeyHex);

    // We should have a 32-byte public key (a 64 character hex string).
    wprintf(L"public key = %s\n",CkStringBuilderW_getAsString(sbPubKeyHex));

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


    CkPrivateKeyW_Dispose(privKey);
    CkStringBuilderW_Dispose(sbPubKeyHex);
