They can be enabled using \&\fISSL_CTX_enable_ct\fR\|(3) or \fISSL_enable_ct\fR\|(3). .PP This library can also be used to parse and examine \s-1CT\s0 data structures, such as Signed Certificate Timestamps (SCTs), or to read a list of \s-1CT\s0 logs. There are functions for: \&\- decoding and encoding SCTs in \s-1DER\s0 and \s-1TLS\s0 wire format. \&\- printing SCTs. \&\- verifying the authenticity of SCTs. \&\- loading a \s-1CT\s0 log list from a \s-1CONF\s0 file. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fId2i_SCT_LIST\fR\|(3), \&\fICTLOG_STORE_new\fR\|(3), \&\fICTLOG_STORE_get0_log_by_id\fR\|(3), \&\fISCT_new\fR\|(3), \&\fISCT_print\fR\|(3), \&\fISCT_validate\fR\|(3), \&\fISCT_validate\fR\|(3), \&\fICT_POLICY_EVAL_CTX_new\fR\|(3), \&\fISSL_CTX_set_ct_validation_callback\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" The ct library was added in OpenSSL 1.1.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2016\-2017 The OpenSSL Project Authors.
