=head1 DESCRIPTION
-X509_get_subject_name() returns the subject name of certificate B<x>. The
+X509_NAME_hash_ex() returns a hash value of name I<x> or 0 on failure,
+using any given library context I<libctx> and property query I<propq>.
+The I<ok> result argument may be NULL
+or else is used to return 1 for success and 0 for failure.
+Failure may happen on malloc error or if no SHA1 implementation is available.
+
+X509_NAME_hash() returns a hash value of name I<x> or 0 on failure,
+using the default library context and default property query.
+
+X509_get_subject_name() returns the subject name of certificate I<x>. The
returned value is an internal pointer which B<MUST NOT> be freed.
-X509_set_subject_name() sets the issuer name of certificate B<x> to
-B<name>. The B<name> parameter is copied internally and should be freed
+X509_set_subject_name() sets the issuer name of certificate I<x> to
+I<name>. The I<name> parameter is copied internally and should be freed
up when it is no longer needed.
-X509_get_issuer_name() and X509_set_issuer_name() are identical to
-X509_get_subject_name() and X509_set_subject_name() except the get and
-set the issuer name of B<x>.
+X509_subject_name_hash() returns a hash value of the subject name of
+certificate I<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 I<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
X509_get_subject_name(), X509_get_issuer_name(), X509_REQ_get_subject_name()
and X509_CRL_get_issuer() return an B<X509_NAME> pointer.
+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 B<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.
+=head1 BUGS
+
+In case X509_NAME_hash(), X509_subject_name_hash(), or X509_issuer_name_hash()
+returns 0 it remains unclear if this is the real hash value or due to failure.
+Better use X509_NAME_hash_ex() instead.
