The Google Pay example is this:
{
"protocolVersion": "ECv1",
"signature": "TJVA95OrM7E2cBab30RMHrHDcEfxjoYZgeFONFh7HgQ",
"signedMessage": "{\"encryptedMessage\":
\"ZW5jcnlwdGVkTWVzc2FnZQ==\",
\"ephemeralPublicKey\": \"ZXBoZW1lcmFsUHVibGljS2V5\",
\"tag\": \"c2lnbmF0dXJl\"}"
}
The workflow say Step 1 is:
1. Fetch the Google signing keys
Do you know where the signing key is located? I cannot find a URL for it;
and I cannot find a Hex or Base64 dump of it. Searching is producing a lot
of irrelevant noise. (Maybe I missed it in my initial read of the page).
