Decrypt folder fails

[lougreenwood]

Hello - first, thanks for creating this!

I am trying to decrypt an 11GB iPhoto library. The source and destination are on a USB flash drive.

I'm using a pub/private key pair for decryption.

macOS Version is 12.1, it's an Intel Mac.

The problem is that the app is not able to decrypt a folder. I've confirmed that I can individual decrypt all files in a given dir, but when I try to decrypt the whole dir, it fails with an error prompt.

Hi,

Thanks for finding and attaching the log.
It appears Synology Cloud Sync does not encrypt MacOS temp dot files (the files that begin with ._).
Your decryption fails as a result of that, I will push a change to fix this problem.

Before I do so, can you try decrypting a temp dot file in your iPhoto library and see if it fails with the same error as in the log? This will help me verify my root cause diagnosis.

Thanks!

Thanks @anojht - I ran 3 experiments, below are the log files:

Attempt to decrypt a specific folder which contains only files and one dot file
synologycloudsyncdecrypttool-backups-dir.log

Attempt to decrypt just the dot file in this folder which errors in the above run
synologycloudsyncdecrypttool.log

Attempt to decrypt a manually created dot file without encryption
synologycloudsyncdecrypttool.log

One more thing - for the last 2 experiments, even though we get errors in the log file, the UI still reports a successful decrypt:

@anojht Sorry to hassle, I realise this is open source and you're doing this in your spare time. But I wondered if there was any news on this?

Thanks!
