Support for TYPE_RSA_CRT_PRIVATE in JCIDE debugger

[kosullivan]

Hi folks,

I've created a very simple applet that tests an RSA encrypt/decrypt of 128 random bytes using a generated KeyPair that uses a 2048-bit RSA key of type TYPE_RSA_CRT_PRIVATE.

http://pastebin.com/qRJYZgq7

I can load this onto a number of smartcards and execute without a problem, but when I run it in the JCIDE debugger I'm getting a CryptoException with reason ILLEGAL_VALUE on the decrypt operation.

Is it possible this is a bug in the debug JCRE, or is it a known unsupported protocol? If so is there a way around it so I can continue to use JCIDE to debug operations of this kind?

Thanks,
kos

Are you using lastest version of JCIDE?
This bug is mentioned before in this forum.

I just downloaded the newest version to confirm and now it is not letting me register/logon!
I've put in my username/password (same one that works on the forum) and it says 'login error!'.

I've confirmed there is no firewall of any kind set up and all other internet access works. I've also attempted registering a new user but that cannot login either. Are the login servers down at the moment? Is there a way I can perform an off-line registration?

Hi,

We were performing some maintenance on our server yesterday, so it may be not stable. But you can login JCIDE successfully now. Sorry for any inconvenience caused.

If you still can't login JCIDE, please let us know. Thanks.

Best regards,

Registration issue is solved thanks.
Back to the topic issue, I have confirmed that the issue is still happening in the latest version (v1.0.5.39, which in JCIDE reports as 2.0.1.70).
If I switch the private key to TYPE_RSA_PRIVATE the code works perfectly. So it's specifically related to TYPE_RSA_CRT_PRIVATE.
