A little fail-safe filesystem designed for microcontrollers (2017)

I worked with mbedTLS on a desktop/mobile project a couple of years ago. I'd previously used OpenSSL, and I wasn't very impressed, but mbedTLS seemed OK: easy to get it building with cmake, easy to get it building on Windows/OS X/iOS/Linux, no actual I/O in the library.

I remember finding integration with libuv a mite annoying, as mbedTLS is rather pull-minded, and I didn't find the documentation for the I/O callbacks super-clear. If your I/O callbacks are making blocking calls of a pipe or socket, though, I'm sure it's much simpler.

Would use again.

(Would not use OpenSSL again.)

mbedTLS is mostly nice but it does suffer from some poor coding practices like large buffers allocated on the stack.

I would warn anyone to stay away from Cypress/Broadcom's WICED OS which has a modified version of mbedTLS with foolish changes to the API that makes porting code extremely challenging.

Reminds me of someone using this gif to describe working with OpenSSL.
