Print an x509 certificate c++

Question

I have an x509 certificate pointer like x509* cert = SSL_get_peer_certificate(connection);

What is the function that I should use to print the complete certificate?

Answer 1

X509_NAME_print_ex系列功能就是您的答案 。

Answer 2

X509_print and X509_print_fp is a simpler choice if you want to print all certificate data. Link to docs

Answer 3

This will print the certificate to console

PEM_write_X509(stdout, peer);
