Cunningham Law (backfired terribly)

Can someone please explain why PGP is needs all of these? All explanations of public key encryption mention any email embedded emails.

And I probably don’t completely understand what PGP is, so please give me a good article or video on it.

    Its about trusting the data you’re decrypting actually came from who you think it came from.

    So the data is signed with your public key, and your public key is published so people can verify the other stuff you publish. Your email is there just so people can communicate back to you…

    You can of course put junk info in the fields if you want, but the purpose of the program is enabling trustworthy lines of communication.

      So the email and username have no cryptographic purpose, they are just there for convenience.

      Thanks I guess…
