The GNU Privacy Guard (GnuPG or GPG)

The GNU Privacy Guard replacement for the PGP is stands for Pretty Good Privacy is computer applications wich is often used in cryptography process authentication for computer data transmission. fisrt introduced  in 1991 by Philip Zimmermann to encrypt data massage transmmission.

Reason the use of PGP is :

• Security
• Simple
• free

 How to get it..?

pgp4win is windows oprations

kleopatra is for unix 

How do I create  GnuPG..?

>>login to your shell account

>>use gpg command to create key

$ gpg --gen-key

   (2) DSA (sign only)
   (4) ElGamal (sign and encrypt)
Your selection?

>>choose the default type that option (1)

About to generate a new ELG-E keypair.
              minimum keysize is  768 bits
              default keysize is 1024 bits
    highest suggested keysize is 2048 bits
What keysize do you want? (1024)

>>the longer  key the more secure it is againts brute-force attacks

Please specify how long the key should be valid.
         0 = key does not expire
      <n>  = key expires in n days
      <n>w = key expires in n weeks
      <n>m = key expires in n months
      <n>y = key expires in n years
Key is valid for? (0) 

>>choos (0) for  lifetime

You need a User-ID to identify your key; the software constructs the user id
from Real Name, Comment and Email Address in this form:
    "Heinrich Heine (Der Dichter) <heinrichh@duesseldorf.de>"

Real name: Monyonk
Email address: monyonk69@gmail.com
Comment: preketek
You selected this USER-ID:
"Monyonk (preketek) <monyonk69@gmail.com>"

Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? O
You need a Passphrase to protect your secret key.

>>then enter your passphrase...!!!

Enter passphrase: monyonk cakep
Repeat passphrase: monyonk cakep
We need to generate a lot of random bytes. It is a good idea to perform
some other action (type on the keyboard, move the mouse, utilize the
disks) during the prime generation; this gives the random number
generator a better chance to gain enough entropy.
