[mbed-tls] Re: What is the right way to use ecp

Hi Gilles Peskine,

The PSA crypto API suggestions and example link was good information. I have tried the same.

But sadly we are using a old version of mbedtls (2.22) which does not have these functions, so I get compilation issues even if I manually add the header files. And a bump to later version might add more issues for me.

So will you be able to suggest me on how I can use legacy crypto API (mbedtls_ecdsa_xxx()) ?

And use case is exactly what was shown in ur example PR. We have a key and a buffer and want's to create a ECDSA signature.
