PGP Internet security related protocol work
how the protocols work
o Pretty Good Privacy (PGP) is an encryption
system used for both sending encrypted emails and encrypting sensitive files.
- First, PGP generates a random session key using one of
two (main) algorithms. This key is a huge number that cannot be guessed,
and is only used once.
- Next, this session key is encrypted. This is done using
the public key of the intended recipient of the message. The public key is
tied to a particular person’s identity, and anyone can use it to send them
a message.
- The sender sends their encrypted PGP session key to the
recipient, and they are able to decrypt it using their private key. Using
this session key, the recipient is now able to decrypt the actual message
