Hi — I'd like to suggest FileShot.io as a useful tool for researchers dealing with datasets.
When sharing datasets that may contain PII or proprietary data — during peer review, with collaborators, or before publication — FileShot ensures the file is encrypted in the browser (AES-256-GCM) before upload. The server stores only ciphertext; the decryption key lives only in the URL fragment.
No account required. MIT licensed, self-hostable.
