GNU gpg is encryption and signing tool.

Systemd does store the entropy in a file, but Lennart says this in the comments of the article: 'we can only credit a random seed read from disk when we can also update it on disk, so that it is never reused. This means /var needs to be writable, which is really later during boot, long after we already needed entropy'. Many programs that use encryption need a good source of random numbers for producing session keys. For example, the PGP program uses random numbers for generating a random key that is used to encrypt the contents of electronic mail messages; the random key is then itself encrypted using the recipient's public key. 252)The PMK is used to generate the which consists of three keys to be used for communication between a STA and AP after they have been mutually authenticated.

The GNU Privacy Guard (GnuPG or GPG) is a free software replacement for the PGP suite of cryptographic software.

GnuPG encrypts messages using asymmetric keypairs individually generated by GnuPG users. The resulting public keys can be exchanged with other users in a variety of ways, such as Internet key servers. They must always be exchanged carefully to prevent identity spoofing by corrupting public key ↔ ‘owner’ identity correspondences. It is also possible to add a cryptographic digital signature to a message, so the message integrity and sender can be verified, if a particular correspondence relied upon has not been corrupted.

How do I create my own GnuPG private and public key

1) Login to your shell account

2) Use gpg command to create the keys
$ gpg --gen-key
Output:

3) Now keys generated, you can list your own key using:
$ gpg -K
OR
$ gpg --list-keys
Output:

Let us try to understand the line pub 1024D/CA7A8402 2007-02-10:

  • pub : Public key
  • 1024D : The number of bits in the key
  • CA7A8402 : The key ID
  • 2007-02-10 : The date of key creation
  • Vivek Gite : The user real name
  • <vivek@nixcraftcorp.com> : The email id

Most important is the key ID i.e. CA7A8402. Make sure you use powerful passphrase to protect keys and not the easy one.

4) To list secret key, type the command:
$ gpg --list-secret-keys
