cannot verify signature #715

Closed dreamlin987 closed 11 months ago

dreamlin987 commented 1 year ago

Why do I verify the data returned after Google payment that does not go through the grid successfully, and it always fails to verify the signature, so how to check or solve it?

dreamlin987 commented 1 year ago

String decryptedMessage = new PaymentMethodTokenRecipient.Builder() .fetchSenderVerifyingKeysWith( GooglePaymentsPublicKeysManager.INSTANCE_TEST ) .recipientId("GooglePayPasses") .protocolVersion("ECv2") .addRecipientPrivateKey("MIGHAgEAMBMGByqGSM49AgEGCCqGSM49AwEHBG0waXXXXXX") .build() .unseal(tokenData);
