Hello!
Thanks for checking out encrypted email communication. I use protonmail for secure end-to-end encrypted mail. You can download my public-key-files here to send me PGP-encrypted email from any platform if you like. Please download the public key depending on the address you write to: for mail(at)matthiasring(dot)com click here, for inbox(at)matthiasring.com click here and import the keys to your PGP-application of choice. Please attach your key to the first message you send to me, sign it and inform me, that you like to use encrypted mail, so I can set it up correctly. Thanks for participating!
