=pod =head1 NAME ct - Certificate Transparency =head1 SYNOPSIS #include =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 B() or B(). 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. =head1 SEE ALSO L, L, L, L, L, L, L, L =cut
