Crypto AES Encrypt Method throws NotImplementedException

NETMF & Gadgeteer

I’m trying to test the Crypto AES example on the Wiki. I have not modified the code and I’m using a fresh project. When I run it in the emulator, it runs successfully. However, when I run in debug mode on the Domino controller, I get the following error:


The thread '<No Name>' (0x2) has exited with code 0 (0x0).
    #### Exception System.NotImplementedException - 0xca000000 (1) ####
    #### Message: 
    #### Microsoft.SPOT.Cryptography.Key_RSA::Encrypt [IP: 0000] ####
    #### Program::Main [IP: 0062] ####
A first chance exception of type 'System.NotImplementedException' occurred in Microsoft.SPOT.Native.dll
An unhandled exception of type 'System.NotImplementedException' occurred in Microsoft.SPOT.Native.dll

Is this not supported on Domino?

Wait for MF 4.2. Should be available from GHI within two months.

AES is too big and slow for these small devices. Use Spider or similar device.

We provide XTEA in our libs for these small devices

Got it. That’s what I figured. I don’t really need it. I was just going through the wiki and trying different samples.

I added the following note under Hardware Requirements on the Crypto AES wiki page:

Not available on USBizi based boards.
