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_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 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_get_subject_name(), X509_get_issuer_name(), X509_REQ_get_subject_name() and X509_CRL_get_issuer() return an X509_NAME pointer.

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.
