Simple PGP Guide

Preface
you MUST include the header and footer segments containing ----begin/end public key block---- when saving keys to file or else you will encounter an error with importing (file extension doesn't matter, you could just use none)

MAKE SURE YOUR PUBLIC KEY IS SENT SEPARATE OUTSIDE THE ENCRYPTED TEXT (SAME EMAIL), YOU WILL ONLY NEED TO INCLUDE THE KEY FOR YOUR FIRST EMAIL SO THE VENDOR IS ABLE TO ENCRYPT COMMS BACK TO YOU

---

iOS
1) download PGPro - App Store
2) locate and save vendors pgp key to file

(i dont have an iPhone to test so these steps are assumed from app store screenshots)

3) navigate to "keychain" tab in pgpro, then tap the + button at top right and import your key file(s)
4) navigate to "encryption" tab → "select contacts" and pick vendor's key from keychain
5) type message and copy encrypted text to clipboard
6) send email to vendor with encrypted text AND your public key (i would assume you can get this in PGPro by selecting your key in keychain tab and then tapping the share button in the top right — i typically include the full text appended but you could just attach a file with your key)

---

Android
1) download OpenKeychain - F-Droid / Google Play
2) locate and save vendors pgp key to file
3) navigate to "keys" tab on sidebar, then tap the + button at bottom right and import key file(s)
4) navigate to "encrypt/decrypt" tab on sidebar
5) select "encrypt text", select vendors key, type message, then tap the copy icon at the top right
6) send email to vendor with encrypted text AND your public key (to locate this in openkeychain, select your own key entry from the "keys" tab and then use the copy button located on the left side of the QR code)

---

Windows + MacOS/Linux
1) download Kleopatra
— a) For Windows - Gpg4win (contains Kleopatra as add-on)
— b) MacOS/Linux - App Store (alternatively, you could run the command sudo apt install kleopatra from terminal

2) locate and save vendors pgp key to file
3) open kleopatra, then select the "import" button on the top ribbon bar and import key file(s)
4) open a text editor (any will work), type out the message you want to send and copy it to your clipboard in clear text
5) in your taskbar, right click the kleopatra icon, navigate to "clipboard" then select "encrypt..."
6) in the encrypt window, select "add recipient...", select your vendor's key and then toggle the "openpgp" option (if it isn't done automatically)
7) send email to vendor with encrypted text AND your public key (to locate this in kleopatra, right-click your own key entry from the main window, select "details", then select "export" at the bottom and copy all the text that appears in the new pop-up window (you can remove all the lines containing "Comment: ...")

Thanks @xenxra for posting. This is very helpful.

Thanks for writing up this guide Xenxra.

I'm new to PGP and using OpenKeychain. I have been sending messages between two burner phones.

Is it normal for decrypted messages to say "signed by an unconfirmed key" ?

It shows up on both phones when I decrypt the messages.

Anytime I add/save a PGP key it's always "unconfirmed" so I'm assuming it's normal?

I'm able to encrypt and decrypt messages successfully . It just the "unconfirmed key" that confuses me. Thanks

Edit: nvm, figured it out. I confirm fingerprint.

Legit the best thing to do for your opsec over email.

Idk why people think this is hard and don't do it, it should be standard. In fact, I would say that if you communicate with me via email, I will not respond to any non-pgp emails.

Def good guide thanks @xenxra

Generally it is frowned upon in the security community to use pgp on phones unless it’s a graphene etc.

I totally understand why the option is being given though. Bc people just just won’t use desktop lol. I’m not sure if I read it but remember never to use your real email address or have any identifiers to lead back to you.

Like obv this is not my real email right? Lol

Thanks @xenxra good work

Brilliant post. Thanks for writing this up.

I hope this isnt a super dumb question but what does "in clear text" mean specifically? like see through font? or just not a jumbled up hard to read message? Im guessing that this is a dumb question seeing how no one else has asked it lol

I think in this context it is pretty much synonymous with 'plain text'. It just means "everyday" text that is unencrypted and without any special formatting like RTF (Rich Text Formatting).

I don't how necessary it was to word it this way because anytime text is copied to the clipboard using right-click>copy (for example on Windows), it is stored in memory as un-formatted and unencrypted WYSIWYG (What You See Is What You Get) text. ...Nonetheless, an excellent how-to by xenxra.
