/*
By default wolfSSL has a very conservative configuration that can result in
connections to servers failing due to certificate or algorithm problems.
To remedy this issue for libcurl I've generated this options file that
build-wolfssl will copy to the wolfSSL include directories and will result in
maximum compatibility.

These are the configure options that were used to build wolfSSL v5.1.1 in
mingw and generate the options in this file:

C_EXTRA_FLAGS="\
  -Wno-attributes \
  -Wno-unused-but-set-variable \
  -DFP_MAX_BITS=16384 \
  -DHAVE_SECRET_CALLBACK \
  -DTFM_TIMING_RESISTANT \
  -DUSE_WOLF_STRTOK \
  -DWOLFSSL_DES_ECB \
  -DWOLFSSL_STATIC_DH \
  -DWOLFSSL_STATIC_RSA \
  " \
./configure --prefix=/usr/local \
  --disable-jobserver \
  --enable-aesgcm \
  --enable-alpn \
  --enable-altcertchains \
  --enable-certgen \
  --enable-des3 \
  --enable-dh \
  --enable-dsa \
  --enable-ecc \
  --enable-eccshamir \
  --enable-fastmath \
  --enable-opensslextra \
  --enable-ripemd \
  --enable-sessioncerts \
  --enable-sha512 \
  --enable-sni \
  --enable-tlsv10 \
  --enable-supportedcurves \
  --enable-tls13 \
  --enable-testcert \
  > config.out 2>&1

Two generated options HAVE_THREAD_LS and _POSIX_THREADS were removed since they
are inapplicable for our Visual Studio build. Currently thread local storage is
only used by the Fixed Point cache ECC which we're not enabling. However even
if we later may decide to enable the cache it will fallback on mutexes when
thread local storage is not available. wolfSSL is using __declspec(thread) to
create the thread local storage and that could be a problem for LoadLibrary.

Regarding the options that were added via C_EXTRA_FLAGS:

FP_MAX_BITS=16384
https://www.yassl.com/forums/topic423-cacertorgs-ca-cert-verify-failed-but-withdisablefastmath-it-works.html
"Since root.crt uses a 4096-bit RSA key, you'll need to increase the fastmath
buffer size.  You can do this using the define:
FP_MAX_BITS and setting it to 8192."

HAVE_SECRET_CALLBACK
Build wolfSSL with wolfSSL_set_tls13_secret_cb which allows saving TLS 1.3
secrets to SSLKEYLOGFILE.

TFM_TIMING_RESISTANT
https://wolfssl.com/wolfSSL/Docs-wolfssl-manual-2-building-wolfssl.html
From section 2.4.5 Increasing Performance, USE_FAST_MATH:
"Because the stack memory usage can be larger when using fastmath, we recommend
defining TFM_TIMING_RESISTANT as well when using this option."

USE_WOLF_STRTOK
Build wolfSSL to always use its internal strtok instead of C runtime strtok.

WOLFSSL_DES_ECB
Build wolfSSL with wolfSSL_DES_ecb_encrypt which is needed by libcurl for NTLM.

WOLFSSL_STATIC_DH:    Allow TLS_ECDH_ ciphers
WOLFSSL_STATIC_RSA:   Allow TLS_RSA_ ciphers
https://github.com/wolfSSL/wolfssl/blob/v3.6.6/README.md#note-1
Static key cipher suites are deprecated and disabled by default since v3.6.6.
