Understanding File Metadata, Hashes, and Evidence Certificates

Uploaded attachments can include file metadata, a SHA-256 hash, version records, and evidence export tools. Availability depends on the file, processing results, and your access.

Review attachment details

Open the attachment details to review its recorded information and available metadata. Processing may be pending, completed, failed, or unsupported. Missing metadata does not necessarily mean the upload failed.

What a file hash means

A SHA-256 hash identifies the file's bytes and helps detect changes or duplicate content. It does not establish that the original content was truthful or accurate.

Export an evidence certificate

  1. Open Attachment Details for a file stored in CaseWyze.
  2. Choose Export Evidence Certificate from the actions menu when available.
  3. Allow verification and package creation to finish.
  4. Review the downloaded ZIP, which contains the attachment bytes, a PDF certificate, a signed JSON manifest, and verification instructions.

CaseWyze verifies the exported bytes against its preserved record and checks available version receipts and signatures. If verification fails, export is blocked.

Scope of the certificate

The certificate establishes that the export matches the version held by CaseWyze at verification time. It does not establish authenticity before upload or determine legal admissibility.

A cloud link has no preserved file bytes or CaseWyze file hash. Upload a source export if you need stored-file evidence handling.
