How to unencrypt attachments in bulk

[JooHyun Park]

Hi,

We're encrypting document files internally using a DRM program.

In order to unencrypt, the file is directly selected and unencrypted.

All of the confluence attachments are encrypted with DRM and uploaded.

I want to unencrypt all of the files before I migrate to Cloud.

The attachments directory is registered with all attachments extension removed and renamed, making it difficult to decrypt the entire directory.

The amount of attachments is too large to download, encrypt, and upload files while browsing all pages.

Is there a way to download the attached files collectively and unencrypt them from the directory and upload them again?

Thanks, Levi

Why does that make it difficult to decrypt?

Your best option is to simply decrypt them in-place on the server

Because it is a program that determines whether or not to encrypt and decrypt files by looking at the extension of the file. Encrypted files are also recognized as unencrypted files without extensions.

If it's the best way to decrypt directly from the server, I'll have to ask the encryption program vender too.

Hmm, that's a pretty weak way to do security, but it won't affect a decryption run - for each file, ask the program to decrypt it - if it's not encrypted, the app should say "nope, not encrypted" so you can move on to the next one.
