File Verification

[c0fe]

I would like to propose a feature:

The ability to have all files that are uploaded to be verified against their source using a hash such as SHA-256 or FNV. I am not sure which hash would be preferred but something that is secure would be great.

A checksum feature was introduced in Nextcloud 10

owncloud/core#21997 maybe @rullzer can tell more

[rullzer]

No that just stores the checksum. We don't verify server side.
That functionality is not there.

I have had weird things happen during upload with Owncloud, I have now more preference for Nextcloud but I would like to see this feature implemented to give a peace of mind.

would be a great feature and improving data reliability

Also think that such feature could make sense. Hope I'm right :)

I think this is something to have an external app.

As this sounds like a nice feature, the requests for this are quite low. Currently there a no plans to implement such a feature and there is an app that crosses some of those features: https://apps.nextcloud.com/apps/checksum. Thus I will close this ticket for now. This does not mean we don't want this feature, but it is simply not on our roadmap for the near future. If somebody wants to implement this feature nevertheless we are happy to assist and help out.
