Unable to generate gpg keys in linux

I'm not able to generate GPG keys in linux

sudo gpg --gen-key      # This is the command to try to generate key

error

You need a Passphrase to protect your secret key.

gpg: problem with the agent: Timeout        
gpg: Key generation canceled.

Please let me know where I'm doing wrong

Solution

Please check with this

1) Run the gpg-agent command:

gpg-agent --daemon --use-standard-socket --pinentry-program /usr/bin/pinentry-curses

2) Generate enough entropy

sudo rngd -r /dev/urandom

3) Finally run the gpg command to generate the key:

gpg --gen-key

please run all commands with non-root user only

Please login with same user,which is used to create gpg keys.

1.We will export both our public key and private key as follows:

  user$ gpg --export -a -o mypublickey.txt [email protected]
  user$ gpg --export-secret-key -a -o myprivatekey.txt [email protected]
  user$ ls my*

myprivatekey.txt mypublickey.txt
