Working of GPG key encryption.

If someone wants you to send a confidential file.
########################################

1)   Generate  gpg keys from your local machine and provide them your public key.

2)   Then they will encrypt that file with your public key provided by you via mail or chat.

3)   Now after encryption they will send that encrypted file to you.

4)   Now you can decrypt the file with the private key resides in your local machine.

Useful commands.
###############

Generate gpg key

# gpg --gen-key

Export a public key 

# gpg --armor --export ramesh > ramesh-pub-asc.gpg

 Import a public key

 # gpg --import FileName
If you want to send a file
#####################

1)   Ask his/her the public key.

2)   Import the public key.

3)   encrypt the file

4)   Send them the file.


That is all , Thanks,

Some time when we try to reset the password of our user in linux it will show as simple and systematic as below: BAD PASSWORD: it is too simplistic/systematic no matter how hard password you give it will show the same. Solution: ######### Check if your password is Ok with the below command, jino@ndz~$ echo 'D7y8HK#56r89lj&8*&^%&^%#56rlKJ!789l' | cracklib-check D7y8HK#56r89lj&8*&^%&^%#56rlKJ!789l: it is too simplistic/systematic Now Create a password with the below command : jino@ndz~$ echo $(tr -dc '[:graph:]' 7\xi%!W[y*S}g-H7W~gbEB4cv,9:E:K; You can see that this password will be ok with the cracklib-check. jino@ndz~$ echo '7\xi%!W[y*S}g-H7W~gbEB4cv,9:E:K;' | cracklib-check                 7\xi%!W[y*S}g-H7W~gbEB4cv,9:E:K;: OK Thats all, Thanks.
