USE CASES

When to use Encrypt / decrypt a file?

Encrypt a local file with AES-256-GCM and a PBKDF2-derived password key before storage or transfer.

  • Protect an export before cloud storage
  • Encrypt an archive before sending
  • Restore a .wtsenc file with its password

Your data stays in the browser

Processed content is not uploaded to WorkToolset. Required libraries may be loaded by the site, but the file stays in the browser.

GOOD TO KNOW

Limitations to know

  • Losing the password makes the data unrecoverable.
  • The content is encrypted, but the original file name remains readable in the .wtsenc format header.
  • Very large files can exceed available browser memory.
  • For regulated or high-assurance requirements, use an audited dedicated encryption product.
HOW IT WORKS

A straightforward workflow.

  1. 1Prepare the required input and choose useful options.
  2. 2Review previews, warnings and limitations before export.
  3. 3Download a new copy or report: the original stays unchanged.
