ct - Certificate Transparency
#include <openssl/ct.h>
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.
