Skipping undecryptable dir name: illegal base32 data

Theprez · January 2, 2025, 1:43am

What is the problem you are having with rclone?

I'm unable to mount or copy files from a remote encrypted bucket on Backblaze B2. I get this error and am unsure what to do:

Skipping undecryptable dir name: illegal base32 data at input byte 3

When I view the bucket, it appears the root directory names are not encrypted but everything under the directory is.

Run the command 'rclone version' and share the full output of the command.

rclone v1.68.2

os/version: Microsoft Windows Server 2019 Standard 1809 (64 bit)
os/kernel: 10.0.17763.6659 (x86_64)
os/type: windows
os/arch: amd64
go/version: go1.23.3
go/linking: static
go/tags: cmount

Are you on the latest version of rclone? You can validate by checking the version listed here: Rclone downloads

Yes

Which cloud storage system are you using? (eg Google Drive)

Backblaze B2

The command you were trying to run (eg `rclone copy /tmp remote:tmp`)

rclone mount backblazecrypt: c:\temp -v

Please run 'rclone config redacted' and share the full output. If you get command not found, please make sure to update rclone.

Clearly you put unencrypted content inside your crypt (backblaze:FILESVR1). Most likely by mistake when accessing backblaze: remote directly.

They do not belong here. Delete them and all will work.

If your goal is to keep both encrypted and not encrypted data in the same bucket then you should separate them, e.g. put all encrypted data in backblaze:FILESVR1/encrypted
