Digital Wallet ​

Generating a Google Wallet Key: ​

To generate a Google Wallet key, follow these steps via the Google Cloud Console:

  1. Go to Google Cloud Console and create a new key:
    • Create credentials -> Service Account -> Create
  2. Create a new private key file:
    • Edit key (pencil icon) -> Keys -> Add Key -> JSON
  3. Delete old or leaked keys:
    • Edit key (pencil icon) -> Keys -> Delete (trash icon)

Save the JSON file as google.json in your keys folder.

Certificate for Apple Wallet: ​

To generate an Apple Wallet key using a CSR file (must end with .certSigningRequest), run the following command:

bash
openssl req -new -newkey 2048 -nodes -keyout FoodsharingAppleWallet.key -out csrFoodsharingAppleWallet.certSigningRequest

Use the following details when prompted:

  • Country Name (2 letter code) [AU]: DE
  • State or Province Name (full name) [Some-State]: Germany
  • Locality Name (eg, city) []: Köln
  • Organization Name (eg, company) [Internet Widgits Pty Ltd]: foodsharing e.V.
  • Organizational Unit Name (eg, section) []: foodsharing.de
  • Common Name (e.g. server FQDN or YOUR name) []: foodsharing.de
  • Email Address []: (apple account email)

For the additional attributes, leave them empty:

  • Challenge password []:
  • Optional company name []:

After that, upload the CSR file to the Apple website and you'll receive a pass.cer file.

Steps on Apple Website: ​

  • Go to Apple Developer

  • Pass Type ID Certificate -> Continue

  • Enter your Pass certificate Name: Foodsharing Production

  • Pass Type ID: pass.de.foodsharing.ausweis -> Continue

  • Upload the certificate -> Continue

  • Download the certificate

Generating the PEM and P12 Files: ​

  1. Convert the pass.cer file to pass.pem using the following command:

    bash
    openssl x509 -in pass.cer -inform DER -out pass.pem -outform PEM

  2. Then, use the pass.pem and the private key to generate the apple.p12 certificate:

    bash
    openssl pkcs12 -export -out apple.p12 -inkey FoodsharingAppleWallet.key -in pass.pem

Save the apple.p12 file in your keys folder.

Important: The Apple key is only valid for 1 year, so you'll need to create a new one after it expires!
