Google Pay decrypt.

[qoyanchoz]

Hi everyone!
Maybe you can write some documentation or something.
I've been unable to decrypt the payload Google sent me for 2 weeks now.
I don't understand how to use your library because I can't find any examples. If any of you can help, like write an example to decrypt the payload.
That would be great!

Hey, guys!
I'm also finding it difficult to use the library in my projects.
I'm unable to decrypt a payload sent via Google Pay.
If possible someone could write an example to decrypt the payload.
I would be very grateful!

I guess you would like to use GPay integration here:
https://developers.google.com/pay/api/web/guides/resources/payment-data-cryptography
in Go. Unfortunately, this part of Tink is only available in Java, here:
https://github.com/tink-crypto/tink-java-apps/

tink-go does not support this. But you may be able to use this here:
https://github.com/google-pay/tink-jni-examples/
This wraps the Java implementation. Note that this is not maintained by the Tink team and we can't help you with that.

@juergw It will be useful to have official Google Pay token decryption implementation using this library.
