Warp
Private, end-to-end encrypted file transfer by CacheSleuth.
Warp is a private, end-to-end encrypted way to send files and short messages. Your files are encrypted in your browser before they are uploaded, and the decryption key lives in the link fragment, the part after the #, so it never reaches the server. That means CacheSleuth cannot read what you send. Only someone with the full link can.
Warp for iPhone Beta
- Send straight from Photos, Files or any app's Share menu.
- Keeps uploading when you switch apps, with progress on the Lock Screen.
- Opens Warp links in the app and plays videos while they download.
Free. It installs through TestFlight, Apple's app for trying apps before they reach the App Store. Sign in with your CacheSleuth account.
What it does
- Files are encrypted in your browser before upload, so the server only ever holds an encrypted blob.
- The decryption key stays in the link fragment and never reaches the server. CacheSleuth cannot read what you send.
- Store up to 1 GiB, or send up to 20 GiB browser-to-browser as a direct transfer.
- Links expire on a timer you choose: 1 hour, 6 hours, 12 hours or 1 day.
- Links can self-destruct after a set number of downloads.
- Add a password, so the link alone is not enough to open what you sent.
- Videos from an iPhone get an extra copy that plays in any browser. The original is sent too.
- You can also send a message-only share with no files at all.
Easy ways to use it
- Share a file in geocaching messages with someone. The Message Center only allows images, so a Warp link lets you send anything.
- Move a file from your phone to your computer with no cables and no accounts.
- Send a link or a note through text or email without prying eyes.
- Hand a GPX or a puzzle file to a teammate.
- Send photos at full quality instead of the compressed versions message apps attach.
Not for long-term storage
Warp is a transfer tool, not storage. Everything you share deletes itself automatically, after 1 day at the latest.
