I have a friend's public key with the associated email address bla@bla.com. I would like to use the key to send an encrypted email to the email address not@not.com.

Is this possible in R2Mail2 for Android? I can in Thunderbird/Enigmail, but it doesn't seem possible in R2Mail2.

This question came from our site for computer enthusiasts and power users.


Here's an idea for your problem. Had the same as well. Searched a long time to get my Keys to the Android phone.

I work with OSX. There is a tutorial how to Export the keys it seems to be a matter of Key and Certificate conversion. Hope that helps:

Encrypt your message to any public key(s). I also recommend encrypt-to-self. Then send it as an attachment to any address.


No thats not possible within R2Mail2 at the moment. As soon I have time I will implement an option where you can link additional email addressee to an public key.
