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_enable_ct(3) or SSL_enable_ct(3).
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.
