Hi,
I see from the MDRM that the blockencipher and blockdecipher primitives support AES key lengths of 16 bytes.

Is there any way that I can use 24 and 32 byte AES keys with blockencipher and blockdecipher primitives?

thanks
Alex

Hi Alex,

I’ve checked out the MULTOS specifications and yes, you can use 24 and 32 byte AES keys with the block encipher / decipher primitives if the implementation supports those lengths (as documented in the MIR).

I’ll update this in the next release of the MDRM. Thanks for pointing this out.
Chris.
