Create GPG Keys

Create a new GPG key

We will be using GPG for extra security and backups encryption. The commands will store our keys in a hidden directory at /root/.gnupg/:

gpg --gen-key

You will be asked a series of questions that will configure the parameters of the key pair.

Please select what kind of key you want:
   (1) RSA and RSA (default)
   (2) DSA and Elgamal
   (3) DSA (sign only)
   (4) RSA (sign only)
Your selection? 
RSA keys may be between 1024 and 4096 bits long.
What keysize do you want? (2048) 
Requested keysize is 2048 bits
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) 
Key does not expire at all
Is this correct? (y/N) y

Press enter to accept the default "RSA and RSA" keys. Press enter twice again to accept the default keysize and no expiration date.
Type y to confirm your parameters.
