(Go) Generate RSA Key and return Base64 PKCS8 Private Key

Demonstrates how to generate a new 2048-bit RSA private key and returns the Base64 encoded PKCS8 representation of the private key.

    rsa := chilkat.NewRsa()

    var success bool

    // Generate a 2048-bit key.  Chilkat RSA supports
    // key sizes ranging from 512 bits to 8192 bits.
    success = rsa.GenerateKey(2048)
    if success != true {
        fmt.Println(rsa.LastErrorText())
        rsa.DisposeRsa()

    privKey := rsa.ExportPrivateKeyObj()

    // Get the private key in PKCS8 Base64 format
    privKeyPkcs8Base64 := privKey.GetPkcs8ENC("base64")

    // The key in base64 format will start similar to this:
