NAME
       ct - Certificate	Transparency

SYNOPSIS
	#include <openssl/ct.h>

DESCRIPTION
       This library implements Certificate Transparency	(CT) verification for
       TLS clients, as defined in RFC 6962. This verification can provide some
       confidence that a certificate has been publicly logged in a set of CT
       logs.

       By default, these checks	are disabled. They can be enabled using
       SSL_CTX_ct_enable() or SSL_ct_enable().

       This library can	also be	used to	parse and examine CT data structures,
       such as Signed Certificate Timestamps (SCTs), or	to read	a list of CT
       logs. There are functions for: -	decoding and encoding SCTs in DER and
       TLS wire	format.	 - printing SCTs.  - verifying the authenticity	of
       SCTs.  -	loading	a CT log list from a CONF file.
