How to use GPG/PGP to share passwords

Sometimes we need to transmit passwords over unsecured channels, like Slack or email. There are lots of password managers, but their password sharing functionality is less robust than I like. For example, 1Password lets you share passwords, but to do so you must share your entire keychain - which is not useful.

To solve this, we can use public/private keys to transmit messages over any channel, that can only be decrypted by the end user. This is stuff of the future! It seems like it would be complicated, but common use cases are very easy to set up and use!

Setup

syntax = "proto3";
package clibalance;

    rpc Relay(Ping) returns (Pong);
}

message Ping {
    int64 id = 1;
}
