Generate an Ed25519 Key Pair

See more Ed25519 Examples

Demonstrates how to generate a new Ed25519 public/private key pair.

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

Unicode C++

#include <CkEdDSAW.h>
#include <CkPrngW.h>
#include <CkPrivateKeyW.h>
#include <CkJsonObjectW.h>

void ChilkatSample(void)
    {
    bool success = false;

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

    CkEdDSAW eddsa;
    CkPrngW prng;
    CkPrivateKeyW privKey;

    // Generates a new eddsa key and stores it in privKey.
    success = eddsa.GenEd25519Key(prng,privKey);
    if (success == false) {
        wprintf(L"%s\n",eddsa.lastErrorText());
        return;
    }

    // Examine the ed25519 key in JWK format;
    const wchar_t *jwk = privKey.getJwk();

    CkJsonObjectW json;
    json.Load(jwk);
    json.put_EmitCompact(false);
    wprintf(L"%s\n",json.emit());

    // Sample output:
    // {
    //   "kty": "OKP",
    //   "crv": "Ed25519",
    //   "x": "SE2Kne5xt51z1eciMH2T2ftDQp96Gl6FhY6zSQujiP0",
    //   "d": "O-eRXewadF0sNyB0U9omcnt8Qg2ZmeK3WSXPYgqe570",
    //   "use": "sig"
    // }

    // In the above JWK, x is the public key, y is the private key.
    // Both are 32 bytes and are base64-url encoded.
