Generate RSA Public/Private Key Pair and Export to PEM

See more RSA Examples

_LANGUAGE_ example code showing how to generate an RSA public/private key pair and export to PEM files. Go

    success := false

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

    rsa := chilkat.NewRsa()

    // Generate a 2048-bit key.  Chilkat RSA supports
    // key sizes ranging from 512 bits to 8192 bits.
    privKey := chilkat.NewPrivateKey()
    success = rsa.GenKey(2048,privKey)
    if success == false {
        fmt.Println(rsa.LastErrorText())
        rsa.DisposeRsa()
        privKey.DisposePrivateKey()
        return
    }

    pubKey := chilkat.NewPublicKey()
    privKey.ToPublicKey(pubKey)

    // Save the private key in PEM format:
    success = privKey.SavePemFile("privateKey.pem")
    if success == false {
        fmt.Println(privKey.LastErrorText())
        rsa.DisposeRsa()
        privKey.DisposePrivateKey()
        pubKey.DisposePublicKey()
        return
    }

    // Save the public key in PEM format:
    success = pubKey.SavePemFile(false,"publicKey.pem")
    if success == false {
        fmt.Println(pubKey.LastErrorText())
        rsa.DisposeRsa()
        privKey.DisposePrivateKey()
