We are developing an app that can submit oil samples to a 3rd party lab through API. Each of their bottles has a qr code and a tracking number on the bottle. This number tracking number is used for identification in their system. When using their app you can scan the qr code and it brings in the text printed on the bottle. However when we scan the qr code outside of their app an encoded text is read.

Above is a example of a bottle. When scanning the qr code in their app it brings in 48KX-1111059, but when scanned outside of their app you get amabdq0o. Is it possible to find the encryption method/key if the encoded and decoded text is known?
