Is there any way to select SHA-256 when using ShaHash? I was not able to get the SHA-256 functions to work correctly - kept giving me key collisions on different sets of data - so I figured I'd use ShaHash (which works perfectly).

Thanks in advance!

I looked at the PR - the code fix looks good, but it looks like it hasn't been merged yet.

Hi n7ekg,

You are having a conflict between the min() function and the local variable called min inside integer.c.

I've submitted a patch for this, since min/max as a local variable name isn't ideal.
PR #747: https://github.com/wolfSSL/wolfssl/pull/747

However you could also try defining "WOLFSSSL_HAVE_MIN".
./configure CFLAGS="-DWOLFSSSL_HAVE_MIN"

Thanks, David Garske, wolfSSL

No workee sad

I blew away the wolfssl directory and did a git clone, then ran through autogen.sh, configure, and make:

erc@pahdev1 wolfssl (master)$ ./autogen.sh;./configure CFLAGS="-DWOLFSSSL_HAVE_M
IN";make clean;make
