The following macro has been deprecated since OpenSSL 3.0, and can be hidden entirely by defining OPENSSL_API_COMPAT with a suitable version value, see openssl_user_macros(7):
#define X509_NAME_hash(x) X509_NAME_hash_ex(x, NULL, NULL, NULL)
X509_NAME_hash() returns a hash value of name x or 0 on failure, using the default library context and default property query.
X509_get_subject_name() returns the subject name of certificate x. The returned value is an internal pointer which MUST NOT be freed.
X509_set_subject_name() sets the issuer name of certificate x to name. The name parameter is copied internally and should be freed up when it is no longer needed.
X509_subject_name_hash() returns a hash value of the subject name of certificate x.
X509_get_issuer_name(), X509_set_issuer_name(), and X509_issuer_name_hash() are identical to X509_get_subject_name(), X509_set_subject_name(), and X509_subject_name_hash() except they relate to the issuer name of x.
Similarly X509_REQ_get_subject_name(), X509_REQ_set_subject_name(), X509_CRL_get_issuer() and X509_CRL_set_issuer_name() get or set the subject or issuer names of certificate requests of CRLs respectively.
X509_NAME_hash_ex(), X509_NAME_hash(), X509_subject_name_hash() and X509_issuer_name_hash() return the first four bytes of the SHA1 hash value, converted to unsigned long in little endian order, or 0 on failure.
X509_set_subject_name(), X509_set_issuer_name(), X509_REQ_set_subject_name() and X509_CRL_set_issuer_name() return 1 for success and 0 for failure.
X509_CRL_get_issuer() is a function in OpenSSL 1.1.0. It was previously added in OpenSSL 1.0.0 as a macro.
X509_NAME_hash() was turned into a macro and deprecated in OpenSSL 3.0.
