NOW WE ARE GOING TO LEARN ABOUT THE ENCRYPTION IN THE LINUX.______

To ENCRYPT a file open this file in the [VIM] editor .that is must required for encryption.

Like I make a file name [gourav] in vim and add contents like

#vim gourav

My name is govam saddar.  Hay hallo to all use this notes. Bye.

:X___________________________________________type collons +capital [X]   on INSERT mode

Enter encryption key _ _ _ _ _ _ _ _ _

Retype the key _ _ _ _ _ _ _

Successfully done.

:wq!__________________    ________________to save n exit from the file .

Now this file is encrypted

CHECK it bye open in VI editor.

#vi gourav

@!%#$^!&^*(^(!)*_*!_(_&)@(^*!&#%@^#!&^$&I$@^&@$%@&$%@&$*%^!#*^#@

It will show thee encrypted form.

To show the encrypted file in decrypted mode

Open the file in VIM

# vim gourav

@#!$#^!%^!*&!)*^&(^!$@$!#^%!%*)@^!)*@#&^(!&*%#&^!$

E@^%!#$&^@#$

Enter encryption key _ _  _ _ _

But after save it again encrypt. so to make decrypt permanently.

TO MAKE A FILE DECRYPTED FORM___________________________________________

# vim gourav

@#!$#^!%^!*&!)*^&(^!$@$!#^%!%*)@^!)*@#&^(!&*%#&^!$

E@^%!#$&^@#$

Enter encryption key _ _  _ _ _

After put the key it will show u as the original file.

To break encryption after enter the encryption key

:set key=____enter _____________collon+set+space+key+=   to break the encryption

But must know the encryption password it mean who knows the password can only decrypt the file .

okkkk
