Cryptographic Protocol on a PICO

Run this on a PICO. See previous post to explain a CMAC.
The CMAC is working as a module. AEScmac.js
testAEScmac.js uses the module to run the NIST test values.
There are two tests.
Test one expects one long array as input.
Test two allows 16 byte blocks in different locations to be pointed to as input.
In test two if there is a partial block at the end, remember to pad the block. (see the test code for the 320 bit example. Test one inserts the padding.
The output of testAEScmac.js
