Converting code to be compatible with both OpenSSL 1.0.x and 1.1.x[edit]
Small correction to the example at 1.1_API_Changes#Adding_forward-compatible_code_to_older_versions:
HMAC_CTX_reset, and EVP_MD_CTX_free are OpenSSL 1.1 APIs themselves so their use should be avoided in the #if section.
Suggested example:
#if (OPENSSL_VERSION_NUMBER < 0x10100000L) || defined (LIBRESSL_VERSION_NUMBER) static HMAC_CTX *HMAC_CTX_new(void) { HMAC_CTX *ctx = OPENSSL_malloc(sizeof(*ctx)); if (ctx != NULL) HMAC_CTX_init(ctx); return ctx; } static void HMAC_CTX_free(HMAC_CTX *ctx) { if (ctx != NULL) { HMAC_CTX_cleanup(ctx); OPENSSL_free(ctx); } } #endif
Similarly examples for other APIs that I encountered:
#if (OPENSSL_VERSION_NUMBER < 0x10100000L) || defined (LIBRESSL_VERSION_NUMBER) #define EVP_MD_CTX_new EVP_MD_CTX_create #define EVP_MD_CTX_free EVP_MD_CTX_destroy #endif #if (OPENSSL_VERSION_NUMBER < 0x10100000L) || defined(LIBRESSL_VERSION_NUMBER) #define ASN1_STRING_get0_data(x) ASN1_STRING_data(x) #endif

Please update the "No longer works" section[edit]
That section is seriously outdated.
