X509_new(3) OpenSSL X509_new(3)NAME
X509_new, X509_free - X509 certificate ASN1 allocation functions
SYNOPSIS
#include <openssl/x509.h>
X509 *X509_new(void);
void X509_free(X509 *a);
DESCRIPTION
The X509 ASN1 allocation routines, allocate and free an X509 structure, which represents an X509 certificate.
X509_new() allocates and initializes a X509 structure.
X509_free() frees up the X509 structure a.
RETURN VALUES
If the allocation fails, X509_new() returns NULL and sets an error code that can be obtained by ERR_get_error(3). Otherwise it returns a
pointer to the newly allocated structure.
X509_free() returns no value.

SSL_get_peer_certificate(3SSL) OpenSSL SSL_get_peer_certificate(3SSL)NAME
SSL_get_peer_certificate - get the X509 certificate of the peer
SYNOPSIS
#include <openssl/ssl.h>
X509 *SSL_get_peer_certificate(const SSL *ssl);
DESCRIPTION
SSL_get_peer_certificate() returns a pointer to the X509 certificate the peer presented. If the peer did not present a certificate, NULL is
returned.
NOTES
Due to the protocol definition, a TLS/SSL server will always send a certificate, if present. A client will only send a certificate when
explicitly requested to do so by the server (see SSL_CTX_set_verify(3)). If an anonymous cipher is used, no certificates are sent.
That a certificate is returned does not indicate information about the verification state, use SSL_get_verify_result(3) to check the
verification state.
The reference count of the X509 object is incremented by one, so that it will not be destroyed when the session containing the peer
certificate is freed. The X509 object must be explicitly freed using X509_free().
RETURN VALUES
The following return values can occur:
NULL
No certificate was presented by the peer or no connection was established.
Pointer to an X509 certificate
The return value points to the certificate presented by the peer.
