[Trustedjava-support] info about CaCertificate tccert

[francesca f. <fra...@ju...>]

Hi all!

I'm using your Tccert package to create a test certificate for a CA.

I've a question:
is it possible to create a Ca certificate where the public and private 
key of the Ca are created by me?

Another question: when i invoke the CaCertificate construct as follows:

cacert = new CACertificate(properties, null, null);

and i invoke the method:

cacert.getKeyPair().getPrivate()

or

caCert.getKeyPair().getPublic()

do i obtain something?
Does the constructor create a keypair for the Ca?

thank you,
F.F.

Note that the CA functionality of TCcert was only intended to quickly create
a "looks like a real CA" certificate for testing, not for production use.

IAIK-JCE is like a big toolbox you can use to create whatever type
of certificate you like (at an amazing price, too, may I say ;-)

quoting the source of the constructor:

    String keysize = prop.getProperty("privatekeysize");
    if (keysize!=null) {
      keypair_ = Common.generateRSAKeyPair(prop.getPropertyAsInt("privatekeysize"));
    } else {
      Log.info("privatekeysize not specified, using default 2048 bits");
      keypair_ = Common.generateRSAKeyPair(2048);
    }
