===== Certificates and Certification =====

In TapeTrack, a **Certificate** is a digitally-generated form that indicates whether or not a [[object:repository|Repository]] is performing adequately. [[object:repository|Repositories]] can either receive a Certified status or a Refused status.  [[object:repository|Repositories]] gaining a Certificate Refused status have Audit Failures due to either surplus or deficit [[object:volume|Volumes]].

Certificates that have previously been [[master:generate_certificate|generated]] are listed on the Certificate tab in TapeTrack TapeMaster.
