=head1 NAME
|
|
|
|
ct - Certificate Transparency
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/ct.h>
|
|
|
|
=head1 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
|
|
L<SSL_CTX_enable_ct(3)> or L<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.
