Lufthansa Passbook Passes

Test Passes can be generated here: mobile.lufthansa.com/mos/mbptest.jsp

Lufthansa Pass files follow the following naming convention:

lufthansa_xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx.pkpass

xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx is Version 4 UUID (http://en.wikipedia.org/wiki/Universally_unique_identifier#Version_4_.28random.29)

They are stored on disk as a zipped package with the pkpass file extension. 

The top level of the package contains the following files:

    footer.png 

The image displayed on the front of the pass near the barcode. Only seen for Priority Boarding so far.

    icon.png 

The pass’s icon. This is displayed in notifications and in emails that have a pass attached, and on the lock screen. When it is displayed, the icon gets a shine effect and rounded corners.

    logo.png 

The image displayed on the front of the pass in the top left.

    manifest.json 

A JSON dictionary. Each key is the path to a file (relative to the top level of the bundle) and the key’s value is the SHA-1 hash for that file. Every file in the bundle appears in the manifest, except for the manifest itself and the signature.

    pass.json 

A JSON (JavaScript Object Notation) dictionary that defines the pass. Its contents are described in detail in “Top-Level Keys.”

    signature 

A detached PKCS#7 signature of the manifest.json file.

Note: All of the pass’s images are loaded using standard UIImage image-loading methods. This means, for example, the file name of high resolution (retina) version of the image ends with @2x.png.
