I'm getting the publicKeyId from the Public Key with this function:
which ties with the signature correctly.
function findkeyid(){
var openpgp = window.openpgp;
var testPublicKey = sessionStorage.getItem('testPublicKey');
var foundKeys = openpgp.key.readArmored(testPublicKey).keys;
if (!foundKeys || foundKeys.length !== 1) {
throw new Error("Key not readed, or more than one key");
}
var pubKey = foundKeys[0]; foundKeys = null;
var getKeyId = function (key) {
return key.primaryKey.getKeyId().toHex();
}
console.log('publicKeyId '+getKeyId(pubKey));
}
I'm a bit confused by your "PGP key" what is that?
I was hoping that I could extract the publicKeyId from the message and use
that to determine what public Key was used to encrypt the message - this
assumes I have several public keys etc.
