SSL_add_untrusted_cert()

void Ssl::SSL_add_untrusted_cert	(	SSL *	ssl,

Add the certificate cert to ssl object untrusted certificates. Squid uses an attached to SSL object list of untrusted certificates, with certificates which can be used to complete incomplete chains sent by the SSL server.

VerifyConnCertificates()

bool Ssl::VerifyConnCertificates	(	Security::Connection &	sconn,

Validates the given TLS connection server certificate chain in conjunction with a (possibly empty) set of "extra" intermediate certs. Also consults sslproxy_foreign_intermediate_certs. This is a C++/Squid-friendly wrapper of OpenSSL "verification callback function" (OpenSSL_vcb_disambiguation). OpenSSL has a similar wrapper, ssl_verify_cert_chain(), but that wrapper is not a part of the public OpenSSL API.
