I created a RSAPrivateCrtKey in order to get the p prime via the getP() method.
My code:

static RSAPrivateCrtKey prime =  = (RSAPrivateCrtKey) KeyBuilder.buildKey(KeyBuilder.TYPE_RSA_CRT_PRIVATE, KeyBuilder.LENGTH_RSA_512, false);
...
//  initialize the RSAPrivateCrtKey
...
prime.getP(tab, (short)0);

But how to initialize the key? I don't know how to write this part of code.
