Signal attachments not rendering

[thephm]

On Windows Desktop I used to be able to copy attachment files from C:\Users\micro\AppData\Roaming\Signal\attachments.noindex to another folder and append the appropriate suffix like .jpg. After that the file would be seen as an image by Windows. Now this no longer works. My theory is they're now encrypting the files.

thanks to someone on reddit, pointed me to: signalapp/Signal-Desktop#5751 (comment)

Every attachment is encrypted with a unique **per-attachment key** that is locally stored in an encrypted SQLCipher database. The local database encryption key is also [protected by the Electron safeStorage API](https://github.com/signalapp/Signal-Desktop/commit/e449702a3ad4d07a603b1779914810dc77d7efde) which utilizes the system keystore provided by your operating system to restrict access and securely store the database encryption key on supported platforms. Existing attachments will be automatically migrated to the new storage system too.
