Shared key??? PGP works on a public-private key-pair, and unless you’re giving out your private key, it’s not shared with anyone. This is blatant misinformation
The public key is public and there is a single vulnerable private key. Someone can identify you with the use of your public key and if someone gets access to your private key (maybe a solen device) they can decrypt logged messages that used that key. This means they can still get access even if you deleted the messages off your device.
That is indeed a disadvantage of PGP. Unfortunately, it is the most portable method of encryption text at rest at the moment. The moment somebody manages to figure out a way to use the Diffie-Hellman algorithm in a portable manner, I’m sure a lot of people will consider that a viable alternative. Till then, learn about disk encryption to keep your keys safe
Just keep in mind PGP is weaker in the sense that it is easier to break due to its shared key.
Email itself is not exactly a secure protocol
