Generate an ECDSA Key

See more ECC Examples

Demonstrates how to generate an ECDSA key. Go

    success := false

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

    // Create a Fortuna PRNG and seed it with system entropy.
    // This will be our source of random data for generating the ECC private key.
    fortuna := chilkat.NewPrng()
    entropy := fortuna.GetEntropy(32,"base64")
    success = fortuna.AddEntropy(*entropy,"base64")

    ecc := chilkat.NewEcc()

    // Generate a random ECC private key on the secp256r1 curve.
    // Chilkat also supports other curves, such as secp384r1, secp521r1, and secp256k1.

    privKey := chilkat.NewPrivateKey()
    success = ecc.GenKey("secp256r1",fortuna,privKey)
    if success == false {
        fmt.Println(ecc.LastErrorText())
        fortuna.DisposePrng()
        ecc.DisposeEcc()
        privKey.DisposePrivateKey()
        return
    }

    fmt.Println(*privKey.GetXml())

    // Save the private key to PKCS8 encrypted PEM
    // (The private key can be saved in a variety of different formats. See the online reference documentation.)
    success = privKey.SavePkcs8EncryptedPemFile("pemPassword","myPemFiles/eccKey123.pem")
    if success != true {
        fmt.Println(privKey.LastErrorText())
    }

    fmt.Println("finished.")
