C OpenSSL Parse X509 Certificate PEM Here is a sample of OpenSSL C code parsing a certificate from a hardcoded string. Included is basically the output in bash if you parse a cert with command line the openssl command, 'openssl x509 -noout -text -in cert.pem'. C (Cpp) X509getsubjectname - 30 examples found. These are the top rated real world C (Cpp) examples of X509getsubjectname extracted from open source projects. You can rate examples to help us improve the quality of examples.

It isn't a byte array. It is an X509_NAME structure.

Use the X509_NAME functions to retrieve the commonName field as an
X509_NAME_ENTRY structure. Then the field value as an ASN1_STRING. Finally
from that you can get UTF8 format using ASN1_STRING_to_UTF8().
