PKCS#7Viewer for Mac

Developer tool for inspecting Mac App Store receipts.

In English
Version 1.0.2

PKCS#7Viewer overview

PKCS#7Viewer ... Finally, a graphical tool for inspecting ASN.1 parse trees aka Mac App Store Receipts and codesign/SSL certificates encoded in the ASN.1 DER/BER format. Use alone or in conjunction with Tighten Pro code generator.

Aimed primarily at Cocoa developers writing and testing code for In-App Purchase Receipt validation, PKCS#7Viewer can open and inspect almost any PKCS ASN.1 DER/BER encoded container.

Some examples of files in this format:

  • Mac App Store Receipts inside application bundles
  • Mac Developer and Developer ID certificate pairs.
  • Codesigning Certificates
  • SSL certificates
Unlike other tools which show only an abstract version of the App Store Receipt, PKCS#7Viewer.app shows you the parse tree exactly as an ASN.1 parser sees it: a Russian-doll like nested container filled with other nested containers and primitive types.

Easily inspect the basic fields included with every MASReceipt or drill down into details of individual In-App Purchase items. The parse tree hierarchy shows exactly what's been included in the receipt, including undocumented but nevertheless useful receipt fields.

  • Hierarchical view exposes exact structure of all ASN.1 data.
  • English descriptions of cryptic ASN.1 object-identifiers.
  • Receipt inspector reveals receipt and in-app purchase values.
Also includes the searchable corresponding asn1dump (shell tool) output for locating specific fields, textual values or object-identifiers.
