New TLS_CURVE25519 implementation breaks the library for TLS_V12

[Wertzui123]

It looks like the new implementation for TLS_CURVE25519 (based on libtomcrypt and added in #111 / 8346fc2) breaks this library when using TLS 1.2.

I've been investigating this issue for an hour now and finally figured out that you can actually just reproduce it using the standard tlsclienthello.c example. Simply change TLS_V13 to TLS_V12 and you will get the following error message:

LTC_ARGCHK 'b != NULL' failure on line 26619 of file .\examples\../libtomcrypt.

A workaround for this seems to be to just disable curve 25519 using the NO_TLS_CURVE25519 macro, although I'm not sure if this breaks anything (as I don't even really know what curve 25519 is).

Hello!

I will take a look. Until fixed it is ok to disable it, it will use another curve.

Thank you,
