They constitute a promise by a Certificate Transparency (\s-1CT\s0) log to publicly record a certificate. By cryptographically verifying that a log did indeed issue an \s-1SCT,\s0 some confidence can be gained that the certificate is publicly known. .PP An internal representation of an \s-1SCT\s0 can be created in one of two ways. The first option is to create a blank \s-1SCT,\s0 using \fBSCT_new()\fR, and then populate it using: .IP "\(bu" 2 \&\fBSCT_set_version()\fR to set the \s-1SCT\s0 version. .Sp Only \s-1SCT_VERSION_V1\s0 is currently supported. .IP "\(bu" 2 \&\fBSCT_set_log_entry_type()\fR to set the type of certificate the \s-1SCT\s0 was issued for: .Sp \&\fB\s-1CT_LOG_ENTRY_TYPE_X509\s0\fR for a normal certificate. \&\fB\s-1CT_LOG_ENTRY_TYPE_PRECERT\s0\fR for a pre-certificate. .IP "\(bu" 2 \&\fBSCT_set0_log_id()\fR or \fBSCT_set1_log_id()\fR to set the LogID of the \s-1CT\s0 log that the \s-1SCT\s0 came from. .Sp The former takes ownership, whereas the latter makes a copy. See \s-1RFC 6962,\s0 Section 3.2 for the definition of LogID. .IP "\(bu" 2 \&\fBSCT_set_timestamp()\fR to set the time the \s-1SCT\s0 was issued (epoch time in milliseconds). .IP "\(bu" 2 \&\fBSCT_set_signature_nid()\fR to set the \s-1NID\s0 of the signature. .IP "\(bu" 2 \&\fBSCT_set0_signature()\fR or \fBSCT_set1_signature()\fR to set the raw signature value. .Sp The former takes ownership, whereas the latter makes a copy. .IP "\(bu" 2 \&\fBSCT_set0_extensions()\fR or \fBSCT_set1_extensions\fR to provide \s-1SCT\s0 extensions. .Sp The former takes ownership, whereas the latter makes a copy. .PP Alternatively, the \s-1SCT\s0 can be pre-populated from the following data using \&\fBSCT_new_from_base64()\fR: .IP "\(bu" 2 The \s-1SCT\s0 version (only \s-1SCT_VERSION_V1\s0 is currently supported). .IP "\(bu" 2 The LogID (see \s-1RFC 6962,\s0 Section 3.2), base64 encoded. .IP "\(bu" 2 The type of certificate the \s-1SCT\s0 was issued for: \&\fB\s-1CT_LOG_ENTRY_TYPE_X509\s0\fR for a normal certificate. \&\fB\s-1CT_LOG_ENTRY_TYPE_PRECERT\s0\fR for a pre-certificate. .IP "\(bu" 2 The time that the \s-1SCT\s0 was issued (epoch time in milliseconds). .IP "\(bu" 2 The \s-1SCT\s0 extensions, base64 encoded. .IP "\(bu" 2 The \s-1SCT\s0 signature, base64 encoded. .PP \&\fBSCT_set_source()\fR can be used to record where the \s-1SCT\s0 was found (\s-1TLS\s0 extension, X.509 certificate extension or \s-1OCSP\s0 response). This is not required for verifying the \s-1SCT.\s0 .SH "NOTES" .IX Header "NOTES" Some of the setters return int, instead of void. These will all return 1 on success, 0 on failure. They will not make changes on failure. .PP All of the setters will reset the validation status of the \s-1SCT\s0 to \&\s-1SCT_VALIDATION_STATUS_NOT_SET\s0 (see \fBSCT_validate\fR\|(3)). .PP \&\fBSCT_set_source()\fR will call \fBSCT_set_log_entry_type()\fR if the type of certificate the \s-1SCT\s0 was issued for can be inferred from where the \s-1SCT\s0 was found. For example, an \s-1SCT\s0 found in an X.509 extension must have been issued for a pre\- certificate. .PP \&\fBSCT_set_source()\fR will not refuse unknown values. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSCT_set_version()\fR returns 1 if the specified version is supported, 0 otherwise. .PP \&\fBSCT_set_log_entry_type()\fR returns 1 if the specified log entry type is supported, 0 otherwise. .PP \&\fBSCT_set0_log_id()\fR and \fBSCT_set1_log_id\fR return 1 if the specified LogID is a valid \s-1SHA\-256\s0 hash, 0 otherwise. Additionally, \fBSCT_set1_log_id\fR returns 0 if malloc fails. .PP \&\fBSCT_set_signature_nid\fR returns 1 if the specified \s-1NID\s0 is supported, 0 otherwise. .PP \&\fBSCT_set1_extensions\fR and \fBSCT_set1_signature\fR return 1 if the supplied buffer is copied successfully, 0 otherwise (i.e. if malloc fails). .PP \&\fBSCT_set_source\fR returns 1 on success, 0 otherwise. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBct\fR\|(7), \&\fBSCT_validate\fR\|(3), \&\fBOBJ_nid2obj\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" These functions were added in OpenSSL 1.1.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2016\-2017 The OpenSSL Project Authors.
