+\&\fBSCT_validate()\fR will check that an \s-1SCT\s0 is valid and verify its signature.

+The certificate the \s-1SCT\s0 was issued for.

+.IX Header "NOTES"
+A return value of 0 from \fBSCT_LIST_validate()\fR should not be interpreted as a
+failure. At a minimum, only one valid \s-1SCT\s0 may provide sufficient confidence
+that a certificate has been publicly logged.
+\&\fBSCT_validate()\fR returns a negative integer if an internal error occurs, 0 if the
+\&\s-1SCT\s0 fails validation, or 1 if the \s-1SCT\s0 passes validation.
+\&\fBSCT_LIST_validate()\fR returns a negative integer if an internal error occurs, 0
+if any of SCTs fails validation, or 1 if they all pass validation.
+\&\fBSCT_get_validation_status()\fR returns the validation status of the \s-1SCT.\s0
+If \fBSCT_validate()\fR or \fBSCT_LIST_validate()\fR have not been passed that \s-1SCT,\s0 the
+returned value will be \s-1SCT_VALIDATION_STATUS_NOT_SET.\s0
