For this tool we are going to use Keybase.io.
Keybase let us encrypt and decrypt a message an sent it to other keybase users. I plan to sent a message to my friend Toatzin.
To encrypt the message I only need to sign it and then write my passphrase in order to complete the encryption. Once the encryption is done, the program will provide me with a plain text that I can paste and email to Toa.
Once is done I can email it to him and he can decrypt it, the reliable thing about signing our emails is that if someone hacks his email they can’t read it because it has a bunch of random letters and numbers.
Similarly decryption works the same, you receive your signed message and paste it in the decryption box and write your passphrase.
If you are the recipient of the email you can decrypt the message.
