Digitally Signing Passbook Passes

Before you can send Passbooks to your customers' devices, you will need to create and upload an Apple .p12 Certificate. This is created using Apple’s Developer Portal and then the file can be uploaded to our secure servers via the Boarding Pass Console.

SITA will sign the pkpass passbook files on your behalf. Passbook passes must be signed by the issuer to be displayed in the Passbook application.

If you do not specify your airlines certificate and key, SITA's certificate and key will be used to sign all .pkpass boarding passes for your partition.

For development purposes, it is okay for partitions to share a certificate but Passbook updates do not work reliably on phones that have passes from different partitions that share the same certificate/passTypeIdentifier.

Note: Production systems MUST have a unique signing certificate and key for their partition. The generic SITA certificate has a passtype identifier of A dedicated SITA certificate can be created for your partition on request. It will have a passType identifier of where xx is the partition code.

A .p12 Certificate file and password is generated in the iOS Dev Centre at

Note: Both the certificate and key are in a single .p12 file.

For Windows/OpenSSL users, you can convert the .p12 file into PEM file format. PEM is the standard format for OpenSSL and many other SSL tools.

Use OpenSSL to convert the certificate and key into two separate PEM files for importing for uploading into Boarding Pass servers.
