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That section is seriously outdated.
