Currently thread local storage is 70 only used by the Fixed Point cache ECC which we're not enabling. However even 71 if we later may decide to enable the cache it will fallback on mutexes when 72 thread local storage is not available. wolfSSL is using __declspec(thread) to 73 create the thread local storage and that could be a problem for LoadLibrary. 74 75 Regarding the options that were added via C_EXTRA_FLAGS: 76 77 FP_MAX_BITS=16384 78 https://www.wolfssl.com/documentation/manuals/wolfssl/chapter02.html 79 "Since root.crt uses a 4096-bit RSA key, you'll need to increase the fastmath 80 buffer size. You can do this using the define: 81 FP_MAX_BITS and setting it to 8192." 82 83 HAVE_SECRET_CALLBACK 84 Build wolfSSL with wolfSSL_set_tls13_secret_cb which allows saving TLS 1.3 85 secrets to SSLKEYLOGFILE. 86 87 TFM_TIMING_RESISTANT 88 https://wolfssl.com/wolfSSL/Docs-wolfssl-manual-2-building-wolfssl.html 89 From section 2.4.5 Increasing Performance, USE_FAST_MATH: 90 "Because the stack memory usage can be larger when using fastmath, we recommend 91 defining TFM_TIMING_RESISTANT as well when using this option." 92 93 USE_WOLF_STRTOK 94 Build wolfSSL to always use its internal strtok instead of C runtime strtok. 95 96 WOLFSSL_DES_ECB 97 Build wolfSSL with wolfSSL_DES_ecb_encrypt which is needed by libcurl for NTLM. 98 99 WOLFSSL_STATIC_DH: Allow TLS_ECDH_ ciphers 100 WOLFSSL_STATIC_RSA: Allow TLS_RSA_ ciphers 101 https://github.com/wolfSSL/wolfssl/blob/v3.6.6/README.md#note-1 102 Static key cipher suites are deprecated and disabled by default since v3.6.6. 103 */ 104 105 /* wolfssl options.h 106 * generated from configure options 107 * 108 * Copyright (C) 2006-2022 wolfSSL Inc. 109 * 110 * This file is part of wolfSSL.
