Using gpg you can generate private and public keys that can be used to encrypt and decrypt files as explained in this example.
May 28, 2015 This blog describes how to generate a private/public key pair using GPG version 1.4.5. The resulting public key will contain two keys, one key for signing and a subkey for encryption. This key can be used with HCM Fusion SaaS to encrypt/decrypt files as they are transferred to and from the UCM server. Oct 01, 2018 It is a free software and pretty straightforward to install. Before you can use it though, you need to create a key pair first and this may be confusing to beginners. Here are the steps to generate a key pair in GPG4Win Kleopatra: Launch Kleopatra and click on New Key Pair. Jul 01, 2019 The public key, which you share, can be used to verify that the encrypted file actually comes from you and was created using your key. It can also be used by others to encrypt files for you to decrypt. To generate your key pair, open your terminal, and type the following.
Step 1: Create a new GPG key-pair
The bold items mentioned in this example are inputs from user.
Step 2: Export your public key
Step 3: Import others public key
Use –import option to import others public key.
Step 4: Send encrypted message
In this example, let us see how John can send an encrypted message to Bob.
Generate Key Code
John encrypts the input file using Bob’s public key. The example below creates a binary file.
For some reason, if John cannot send the encrypted-binary files to Bob, he can always create a ASCII-encrypted-file as shown below.
Step 5: Read the encrypted message
In this example, le us see how Bob can read the encrypted message from John.
Decrypt the message using your private key.
Decrypt the message using your private key.
Note: After entering the passphrase, the decrypted file will be printed to the stdout.
Use the following command to redirect the decrypted message to a text file.
Additional GPG commands:
You can list all the GPG keys as shown below.
GNU gpg is encryption and signing tool.
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
Output:
$ gpg --gen-key
Output:
3) Now keys generated, you can list your own key using:
OR
Output:
$ gpg -K
OR
$ gpg --list-keys
Output:

Let us try to understand the line pub 1024D/CA7A8402 2007-02-10:
Generate Rsa Key Pair Online
- 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
- <[email protected]> : 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:
Output:
$ gpg --list-secret-keys
Output:
Gpg Generate Rsa Key Pair
