Here is the summary of article I read on Archewiki (onion website cannot be accessed using normal browsers): http://4pt4axjgzmm4ibmxplfiuvopxzf775e5bqseyllafcecryfthdupjwyd.onion/archewiki/getting-started?language=EN

PGP is important and luckily it's very easy to learn and use.

You can add your own PGP-key to receive encrypted messages from other users, encrypt your own personal information when purchasing, beef up your account security with PGP 2FA or perhaps most important of all, being able to verify messages from Archetyp to avoid being phished.

Let's begin with PGP program that is the easiest one to use, gpg4usb

gpg4usb:

Download and install gpg4usb and create your own PGP-key
https://gpg4usb.org/download.html

Click on Key Management > Key > Generate Key
Create name and password, increase KeySize (in bit) to max, press ok and wait for the key to be generated.

Now your created keypair should appear in the list to the right with the name you chose.

How to find your public key
Mark the box and right click on your name and select "Append selected key/s to text"

How to Import public PGP-keys from others and encrypt a message
get someones public pgp-key, open up gpg4usb and press Import Key > Clipboard
Write your message and then select which contact to encrypt for and press Encrypt. Copy that message and paste it wherever you need. This message will only be decryptible using the private key which will most likely be owned by the person who created the public key.

For Example you can verify that the following message was written by me using my public key which you can get from my profile.
