Using my public key to encrypt a simple string causes gpgme to raise an InvalidValue error. It works fine using the key of my employer. Using my key also works fine on the gpg command line and I am able to receive and decrypt mail with it.

Sadly I am kind of lost on how to debug this.. any tips? Thank you very much!

Hello @luto,
Did you find any workaround this issue?
I'm facing the same case.
Thanks!

Hi Vincent! No, sorry. I abandoned the project because of the lack of GPG support in ruby at the time. Best of luck! I hope things have improved.
