Hi,

I would like to use 4096 bit RSA encryption on BB device (for testing I'm using BB 8300 with 4.5.0.52 b75 OS).

Is this possible?  I'm getting exception in this code:

RSAKeyPair sampleKeyPair;
            sampleKeyPair= new RSAKeyPair(new RSACryptoSystem(4096));

Changing 4096 into 2048 fix this exception, but it's not solution for me.

Thanks.

I reply myself.

After reading 'Blackberry Enterprise Soluttion Security, Technical Overview', I've found that i can use 4096 bits encryption algorithm, but Key generation is restricted to 2048 bits (probably performance issue).

So the problem was not with 

new RSACryptoSystem(4096)

but with generating RSAKeyPair.

I would recieve private RSA key from outside, so i don't need to generate one (at least at current state of the project i'm working on)

i'm really curious, if somebody know how to generate 4096 bits RSA  Key.
