PGP? That's for email and isn't great

[-] MigratingtoLemmy@lemmy.world 8 points 1 month ago

That's for encrypting text, regardless of the medium. Explain "not very good"?

Possiblylinux127 seemed like he had founds faults in PGP's encryption which got me interested

Oh, I was just interested in making a pun based on the name. 😂

To be perfectly honest I was under the impression that we had collectively bailed on PGP in favor of GPG, but based on the Wikipedia article it seems like PGP is still getting updates so maybe that's not the case?

[-] MigratingtoLemmy@lemmy.world 3 points 1 month ago

PGP is the protocol, GPG is the implementation. People tend to use GPG because it is FOSS.

Thank you for distilling that down, cleared up all of the confusion I had. Cheers.

It uses the same public key unless you manually change it. You don't get the rolling keys provided by other systems

[-] MigratingtoLemmy@lemmy.world 2 points 1 month ago

I don't think I understand what you're implying. Are you arguing that PGP implements less secure operations because it doesn't have perfect forward secrecy? As far as I know there's not much out there in terms of encryption schemes for data at rest which includes PFS. Even AGE didn't have it last time I checked. If you know about something that does provide PFS for data at rest, let me know

This is a good read. I think it's a good solution if it can be implemented properly. Are there applications you know of that allow you to personally (manually) encrypt text and communicate with another person like GPG does?

https://simplex.chat/

https://signal.org/

You should not be doing manual communications as that opens the door for human error and is time consuming. Also these cryptography protocols are far to complex to easily be used for text.

And using these apps is not always an option. I like simplex, but sometimes email is one of the only options. PGP can be used agnostic of the technology used for transmission, and that's exactly what we need to keep more people private instead of forcing them into a few select applications. If Diffie-Helman can't be used in a transport-agnostic fashion then I do not see much progress in this direction.

[-] possiblylinux127@lemmy.zip 1 points 1 month ago

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

[-] MigratingtoLemmy@lemmy.world 1 points 1 month ago

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

[-] possiblylinux127@lemmy.zip 1 points 1 month ago

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.

[-] MigratingtoLemmy@lemmy.world 1 points 1 month ago

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
