I’m new to Crytomator, so I may have missed something in the online docs.
Does Cryptomator have a built-in checksum to verify integrity of files once they have been updated (cloud sync, etc).
If, yes, what is the algorithm used? I would prefer something stronger like SHA-256 or SHA-512.
If no, then what S/W would you recommend that could do this?
There is no “vault checksum”, since the files are encrypted individually. But each file is encrypted using AES-GCM, which has an authentication tag and is basically an integrity check, see: Vault Cryptography — Cryptomator Documentation
Furthermore, Cryptomator has a “Health Check” feature (accessible via the Vault Options), which checks if the vault structure is intact.
Does that help?
