 int X509_subject_name_cmp(const X509 *a, const X509 *b);

DESCRIPTION

This set of functions are used to compare X509 objects, including X509 certificates, X509 CRL objects and various values in an X509 certificate.

The X509_cmp() function compares two X509 objects indicated by parameters a and b. The comparison is based on the memcmp result of the hash values of two X509 objects and the canonical (DER) encoding values.

The X509_NAME_cmp() function compares two X509_NAME objects indicated by parameters a and b. The comparison is based on the memcmp result of the canonical (DER) encoding values of the two objects. i2d_X509_NAME(3) has a more detailed description of the DER encoding of the X509_NAME structure.

The X509_issuer_and_serial_cmp() function compares the serial number and issuer values in the given X509 objects a and b.

The X509_issuer_name_cmp(), X509_subject_name_cmp() and X509_CRL_cmp() functions are effectively wrappers of the X509_NAME_cmp() function. These functions compare issuer names and subject names of the objects, or issuers of X509_CRL objec
