[Muscle] CardEdge specification ComputeCrypt

Hello,

If direction is DIR_VERIFY, then the CIPHER_FINAL block must contain the
last input data and the signature to verify.

I think the specification must be updated like this:

- - - - - - - - - - - - - - - - - - - - - -

Extended Data when Operation is CIPHER_FINAL and direction is not
DIR_VERIFY:
Byte Data Location
DataChunk Input Data // If Location == APDU

When operation is CIPHER_FINAL and direction is DIR_VERIFY, last data
chunk must be followed by the signature data to be verified.

Extended Data when Operation is CIPHER_FINAL and direction is DIR_VERIFY:
Byte Data Location
DataChunk Input Data // If Location == APDU
DataChunk Signature Data // If Location == APDU

- - - - - - - - - - - - - - - - - - - - - -

Bye, Karsten
