RClone Crypt Hides File Contents from Cloud Providers, But Not Metadata
RClone's crypt remote encrypts file contents and optionally filenames using XSalsa20-Poly1305 before data reaches providers like Dropbox or Google Drive, preventing them from reading stored documents. However, directory structure, approximate file sizes, and access times remain visible to the provider, meaning user behaviour can still be partially profiled. The encryption layer also disables native sync clients, server-side deduplication, delta transfers, file previews, and web access. For regulated or confidential data, experts caution that metadata leakage and encryption key custody must be formally documented before relying on crypt for compliance. RClone crypt is best understood as a confidentiality tool against providers, not a path to anonymity or full control over where data is stored.
