• OpenPGP Forwarding

    From August Abolins@1:153/757 to All on Saturday, September 23, 2023 10:52:10
    An interesting idea, but I'm not sure if it's a good one.

    1. Introduction

    An OpenPGP user might be interested in forwarding their email to
    another user without delegating decryption or interacting beyond
    protocol setup. In this document we outline the changes necessary to
    the OpenPGP protocol to safely allow:

    * Recipients to delegate trust to third parties to read their
    messages;

    * MTAs to act as cryptographic Proxies and transform select
    messages;

    * Forwardees to read the transformed email.

    I don't really understand what problem they are trying to solve here...


    Bye, Wilfred.

    Yeah..it's a bit confusing for me too.

    "Abstract

    An OpenPGP user may want to request their email provider to
    automatically forward some or all of the messages they receive to a
    third party. Given that messages are encrypted, this requires
    transforming them into ciphertexts decryptable by the intended
    forwarded parties, while maintaining confidentiality and
    authentication."

    Have you tried forwarding an encrypted message elsewhere and
    decrypt it from there? Doesn't work for me.

    Yeah, don't really understand why you would want or need this...

    There shouldn't be a problem as long as the pgp payload isn't changed...

    I concur. What's wrong with sending encrypted email to a
    direct destination. I don't understand the need for a "trusted
    3rd party".

    Perhaps this is a ruse by some three-letter agencies to gain
    the opportunity to read encrypted traffic.

    I've tried forwarding encrypting messages that have arrived to
    one of my addresses to another one that I can access later for
    convenience. The latter had trouble processing the blocks.

    I had the same thought...

    Apparently the person associated with the proposal works for
    ProtonMail.

    So he has a companies profit as incentive...
