Thanks! I don't know how I missed this page :-)

Your project is very nice! I built your libtls-bearssl library and
then rebuilt the 'nc' client that comes with LibreSSL against your
libtls.a and libbearssl.a.

Just a minor issue:   " undefined reference to `explicit_bzero' ". I
provided it with a quick hack and I could build  the libreSSL 'nc'
with bearssl  - Here are the executable sizes:
   LibreSSL nc  1,976 KB
   The _same_ nc linked against bearssl and your libtls-bearssl  276
KB  -- Wow!! and it works fine! :-)

(both are built static with musl libc, -Os, stripped)
