# Load the contents of the receipt file
receipt_file = open('./receipt_data.bin', 'rb').read()

# Use asn1crypto's cms definitions to parse the PKCS#7 format
from asn1crypto.cms import ContentInfo
pkcs_container = ContentInfo.load(receipt_file)

# Extract the certificates, signature, and receipt_data
certificates = pkcs_container['content']['certificates']
signer_info = pkcs_container['content']['signer_infos'][0]

// If you don't use underscore.js, use it (http://documentcloud.github.com/underscore/)
// Then, use underscore's mixin method to extend it with all your other utility methods
// like so:
_.mixin({
    escapeHtml: function () {
        return this.replace(/&/g,'&')
            .replace(/>/g,'>')
            .replace(/</g,'&lt;')
