.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
A \fB\s-1CT_POLICY_EVAL_CTX\s0\fR is used by functions that evaluate whether Signed
Certificate Timestamps (SCTs) fulfil a Certificate Transparency (\s-1CT\s0) policy.
This policy may be, for example, that at least one valid \s-1SCT\s0 is available. To
determine this, an \s-1SCT\s0's timestamp and signature must be verified.
This requires:
.IP "\(bu" 2
the public key of the log that issued the \s-1SCT\s0
.IP "\(bu" 2
the certificate that the \s-1SCT\s0 was issued for
.IP "\(bu" 2
the issuer certificate (if the \s-1SCT\s0 was issued for a pre-certificate)
.IP "\(bu" 2
the current time
.PP
The above requirements are met using the setters described below.
.PP
\&\fICT_POLICY_EVAL_CTX_new()\fR creates an empty policy evaluation context. This
should then be populated using:
.IP "\(bu" 2
\&\fICT_POLICY_EVAL_CTX_set1_cert()\fR to provide the certificate the SCTs were issued for
.Sp
Increments the reference count of the certificate.
.IP "\(bu" 2
\&\fICT_POLICY_EVAL_CTX_set1_issuer()\fR to provide the issuer certificate
.Sp
Increments the reference count of the certificate.
.IP "\(bu" 2
\&\fICT_POLICY_EVAL_CTX_set_shared_CTLOG_STORE()\fR to provide a list of logs that are trusted as sources of SCTs
.Sp
Holds a pointer to the \s-1CTLOG_STORE\s0, so the \s-1CTLOG_STORE\s0 must outlive the
\&\s-1CT_POLICY_EVAL_CTX\s0.
.IP "\(bu" 2
\&\fICT_POLICY_EVAL_CTX_set_time()\fR to set the time SCTs should be compared with to determine if they are valid
.Sp
The \s-1SCT\s0 timestamp will be compared to this time to check whether the \s-1SCT\s0 was
issued in the future. \s-1RFC6962\s0 states that \*(L"\s-1TLS\s0 clients \s-1MUST\s0 reject SCTs whose
timestamp is in the future\*(R". By default, this will be set to 5 minutes in the
future (e.g. (\fItime()\fR + 300) * 1000), to allow for clock drift.
.Sp
The time should be in milliseconds since the Unix epoch.
.PP
Each setter has a matching getter for accessing the current value.
.PP
When no longer required, the \fB\s-1CT_POLICY_EVAL_CTX\s0\fR should be passed to
\&\fICT_POLICY_EVAL_CTX_free()\fR to delete it.
.SH "NOTES"
.IX Header "NOTES"
The issuer certificate only needs to be provided if at least one of the SCTs
was issued for a pre-certificate. This will be the case for SCTs embedded in a
certificate (i.e. those in an X.509 extension), but may not be the case for SCTs
found in the \s-1TLS\s0 \s-1SCT\s0 extension or \s-1OCSP\s0 response.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fICT_POLICY_EVAL_CTX_new()\fR will return \s-1NULL\s0 if malloc fails.
