+=head1 NAME
+
+SSL_get_peer_cert_chain, SSL_get0_verified_chain - get the X509 certificate
+chain of the peer
+
+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ STACK_OF(X509) *SSL_get_peer_cert_chain(const SSL *ssl);
+ STACK_OF(X509) *SSL_get0_verified_chain(const SSL *ssl);
+
+=head1 DESCRIPTION
+
+SSL_get_peer_cert_chain() returns a pointer to STACK_OF(X509) certificates
+forming the certificate chain sent by the peer. If called on the client side,
+the stack also contains the peer's certificate; if called on the server
+side, the peer's certificate must be obtained separately using
+L<SSL_get_peer_certificate(3)>.
+If the peer did not present a certificate, NULL is returned.
+
+NB: SSL_get_peer_cert_chain() returns the peer chain as sent by the peer: it
+only consists of certificates the peer has sent (in the order the peer
+has sent them) it is B<not> a verified chain.
+
+SSL_get0_verified_chain() returns the B<verified> certificate chain
+of the peer including the peer's end entity certificate. It must be called
+after a session has been successfully established. If peer verification was
+not successful (as indicated by SSL_get_verify_result() not returning
+X509_V_OK) the chain may be incomplete or invalid.
+
+=head1 NOTES
+
+If the session is resumed peers do not send certificates so a NULL pointer
+is returned by these functions. Applications can call SSL_session_reused()
+to determine whether a session is resumed.
+
+The reference count of each certificate in the returned STACK_OF(X509) object
+is not incremented and the returned stack may be invalidated by renegotiation.
+If applications wish to use any certificates in the returned chain
+indefinitely they must increase the reference counts using X509_up_ref() or
+obtain a copy of the whole chain with X509_chain_up_ref().
+
+=head1 RETURN VALUES
+
+The following return values can occur:
+
+=over 4
+
+=item NULL
+
+No certificate was presented by the peer or no connection was established
+or the certificate chain is no longer available when a session is reused.
+
+=item Pointer to a STACK_OF(X509)
+
+The return value points to the certificate chain presented by the peer.
