Keys for encrypted disks not accepted,

• Moved digital life (medical, finance docs etc) to Synology DS220+ in June 2021. Sensitive files stored using encrypted folders.
• Hit early snag where keys were not working...confident I knew them & spiraled...all the way to recreating folders from scratch.
• From that experience, I wrote down the key to one folders against better judgement.... point being I have 1 key in writing.
• 3 encrypted folders, keys not working for 2 of the 3 folders. 1 working folder is an older backup of folder not opening...same key.
• 1 encrypted folder stays open most times. 1opened as needed (few times a year.)

• Back to a spot where I am trying versions upon versions of keys, more out of desperation and it a downward spiral wasting time.
• Given 1 key is fully documented & typing it generates an error, it puts a pit in my stomach thinking corruption.
• Given 1 folder mounts just fine w/the same password generates that same pit in the stomach of corruption.
• Snapshots are on, have not yet explored....and hard to say when this issue happened when nas isn't rebooted that often.
• DSM 7.0-41890 (recent update available and concerned about updating until folders mount as expected, so no changes there.)

• Synology has been rebooted a few times over the last six months, never and issue even when encrypted folders were mounted.
• Discovered this problem recently because there was a reboot, needed to remount the folder...and bam...Invalid key error.
• Is it possible one can create a key using characters then not accepted when mounting folder? Doubt this is the case when one folder mounts fine, same password....me reaching for reasons.


1) we need a way to mount encrypted folders from DS finder app - like add control panel to the DSM Mobile
2) maybe capitalize F in DS Finder
2) there appears to be no way to dismiss the second popup from DS Finder > Control Panel > Share Folder > (select share) > Encryption > Mount > (enter key) > PopUp reading "Invalid key. lease enter or import a valid key for decryption." > OK button.

When you are having password issues and trying to get through this, this second popup appears inaccessible from the keyboard requiring switching to a mouse to click each and every time. How are accessibility technologies like Jaws handling the popup?

Sorry to hear. This happened once before to me. Neither saved password not key file could unlock the folder. Out of disgust, I deleted the folder, and vowed never again to use Synology's encryption. Good luck.

Turned out I did have a key...so at least not quite as tragic....and..yes...stll disgusted as this was pretty much a core purpose to this synology investment and workflows.
