Cache Oddity Stuff

Using fork of mbed-tls AES implementation I've looked at a bit: https://github.com/newaetech/chipwhisperer/blob/develop/hardware/victims/firmware/crypto/mbedtls/library/aes.c

Important chunks:

• AES_FROUND Definition
• aes_encryption Definition

One round of AES works like this with T-Tables:

# Encodes ioprox data to format used by proxmark, if using a version that doesn't allow you to specify
# the version/facility/cardnumber seperately.

id_str = "XSF(01)66:25342"

version = id_str.split('(')[1].split(')')[0]
facility = id_str.split('(')[1].split(')')[1].split(':')[0]
code = id_str.split(':')[1]

version = int(version, 16) #is this hex? Have only seen 1 or 2 here

# SPI to the FPGA directly instead of the SPI flash.
