Hello Swillis2497,
Thank you for using Apple Support Communities. Based on your post, you can't restore your iPad because it prompts you for encryption password. We'll do our best to assist.
To restore an encrypted backup, you'd need to know the password created to make that backup. Otherwise, you would need to restore the iPad, as new instead of from a backup: About encrypted backups on your iPhone, iPad, or iPod touch (Under section, 'If you can’t remember the password for your encrypted backup'.)
Even if you restored the encrypted backup with the correct password, it will still prompt you for the old passcode, because it's restoring that data to the iPad.
If you originally forgot the iPad passcode, then you'd want to follow: If you forgot your iPhone passcode
Set it up as new (without restoring a backup) but you can sign in to your Apple ID and iCloud accounts to restore what information you can.
Hoping this helps out, take care.
