Uploading modified file as admin
When you upload a modified file in your admin environment, and bFlash metadata has been stored because the original file has been downloaded and decrypted, the system requires it to be a decrypted slave file. If the file can not be encrypted, the system will produce an error. To circumvent this, check the "Reset bFlash metadata" checkbox.
Note: Currently, the encryption does not do any server-side validation. So the "Attempt to encrypt file" step in the diagram will always succeed. Except for when the API is down.
