Pretty Good Privacy is not really as complicated as it seems. Let's take a look at an example.
Person A (the sender), wants to send his friend, Person B (the recipient), an email, but he wants it to be private.
Now, person B (the recipient) needs to generate a private key and a public key. See how to generate your personal key with Mailfence . Watch our video and find out how to add your keys to your account .
Person B then sends his public key to Person A.
Using the public key just received, Person A can encrypt his email.
You can now send the encrypted email to person B.
Finally, to read the message, person B needs to decrypt it belize whatsapp number data 5 million using his private key. Anyone else who intercepts the email will not be able to read it, because it would be incomprehensible to them.
What is the difference between PGP, OpenPGP and GnuPG?
We have already covered how Phil Zimmerman, the creator of PGP, submitted OpenPGP as a proposal to the IETF in 1997 to avoid patent issues.
There is also a third participant in this story, and that is GnuPG , or Gnu Privacy Guard (GPG).
Gnu Privacy Guard was developed two years after OpenPGP in 1999, and is based on the OpenPGP standard that Zimmerman submitted to the IETF. It is a free alternative to PGP that users can download, modify, distribute, and use to encrypt/decrypt PGP and OpenPGP files.
To recap : the original PGP was developed in 1991 and then bought by Symantec, then OpenPGP was created, which was submitted and approved by the IETF in 1997 as a free alternative, and then GPG came out in 1999, based on the OpenPGP standard.
How does it work ?
