Searching -- What libraries exist for doing RSA on a 16-bit microcontroller?

    <<TODO>> It SAYS it's RSA for PIC24!!!

    <<TODO>>  This says it's compatible with PIC24!

    <<TODO>> look through these

    RSA on 8-bit microcontrollers


======== journal articles ========

https://www.iacr.org/archive/ches2004/31560117/31560117.pdf
    Journal article on implementing RSA on 8-bit microcontrollers
    ^^ It gives a sense of how fast it can run, and gives tips for optimizing it
       on a microcontroller.

    ECC on 8-bit microCPU

    ECC on 8-bit, 16-bit, and 32-bit microCPUs


<<TODO>> Would any of the "normal" libraries designed for 32-bit or 64-bit processors work on a
16-bit processor?  All processors must have some kind of BigNum library that allows them to do
1024-bit etc math, and 'int' isn't the same size everywhere.
