.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Signed Certificate Timestamps (SCTs) are defined by \s-1RFC 6962,\s0 Section 3.2.
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.
