I made a gpg Hat (lemmy.ml)

I recently have been playing around with GPG (its pretty fun!) And decided to make a hat with my public key on it!

Its a fun conversation starter at walmart, when somebody asks what it is? It activates my tism, and i get to talk about computer science! Its also important to teach others the importants of encryption especially as of one day ago the EFF made a post talking about yet another bill trying to go after encryption.

The keen eyed among you see i have blocked out certain parts of my key, this is because i have a key for this hat exclusively and would like to see if anybody i talk to about encryption in real life bothers to email me. I know its not much but i enjoy it!

I laser etched the leather, and hand stitched it to the hat.

I know this is more kinda clothing stuff, but it just didnt feel right posting a hat with a gpg key on a fasion/clothing community.

Hope you enjoy My little project >:) hehe

It should be if there is chunks missing its unusable. At least thats my thinking, since gpg is usually a binary and ascii armor makes it human readable. As long as a person cannot guess the blacked out parts, there shouldnt be any data.

Kinda like binary if your missing bits of binary in a program it should be unreadable

--edit

im full of shit Its base64 and you can somewhat decode it

were you careful to be sure to get the parts that have the key’s name and email address?

you are mistaken. A PGP key is a binary structure which includes the metadata. PGP's "ascii-armor" means base64-encoding that binary structure (and putting the BEGIN and END header lines around it). One can decode fragments of a base64-encoded string without having the whole thing. To confirm this, you can use a tool like xxd (or hexdump) - try pasting half of your ascii-armored key in to base64 -d | xxd (and hit enter and ctrl-D to terminate the input) and you will see the binary structure as hex and ascii - including the key metadata. i think either half will do, as PGP keys typically have their metadata in there at least twice.

Yeah i realized this after i got to work and lookup up what gpg uses for ascii armor. Its base64, i used base64 -d and i could get some parts of my key. The photo has been updated to remove alot more of the key.

Major fuckup on my part.

But i learned that ASCII armor is base64 i guess.
