I'm currently trying the codename one framework and I would like to know if there was a way to store keypair generated by the bouncy castle library by any chance ?
I tried to store keys using Storage and Preferences but always resulting the same Exception

You need to save the byte array related to the key and not the key object. E.g.
byte[] b = key.toASN1Primitive().getEncoded();
And to restore:
RSAPublicKey key = RSAPublicKey.getInstance(b);
Haven't tried it but looking at the code I think this should work.
