Hello,

Recently Intel notify us about TinyCrypt end of life because Zephyr is
one major project still using it.

In order to respond it properly, the Zephyr PSIRT team needs to
understand how TinyCrypt is currently used on Zephyr. An
initial research shows that only the Bluetooth subsystem depends
(exclusively) on this library for hashing and elliptic curves.

We need the community feedback to know which other places are using
TinyCrypt, which features are being used and finally what is the most
constraint platform currently supported that is using TinyCrypt.

Based on the answers we will come up with some proposals to mitigate
this problem.

Regards,
Flavio Ceolin
