If you are on version 2.1.17 or greater, paste the text below to generate a GPG key pair. $ gpg -full-generate-key; If you are not on version 2.1.17 or greater, the gpg -full-generate-key command doesn't work. Paste the text below and skip to step 6. $ gpg -default-new-key-algo rsa4096 -gen-key. The Red Hat Customer Portal delivers the knowledge, expertise, and guidance available through your Red Hat subscription. Creating GPG Keys Using the Command Line. 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.
The following guide shows the detailed instructions for generating a PGP key-pair for sending and receiving encrypting emails.
At the end of this session, you will have a PGP public and private key-pair generated on your computer.
Installing Gpg4Win
- Download Gpg4Win from www.gpg4win.org
- Double-click on the downloaded file to install the application
- Now go to the start menu and launch Kleopatra
- Kleopatra is a PGP keychain manager application. The main window should look like as below.
Generating a PGP Key-pair

- Now click on File => New Certificate
- Select the 'Create a personal OpenPGP key pair' option
- Enter your name and emails address into the following form

- Review your settings then click on the 'Create Key' button if everything is all right
- Now select a strong passphrase. This will protect your private key on your hard disk with encryption.
Warning: Never reuse your passwords
Choose a brand-new passphrase that you have never used on any other service (e.g. Gmail) before
Azure api management generate subscription key free. As mentioned by nmbrphi, garethb, we can control what end user see in browser network tab.And as we do not have user authentication available in system and only have IP authentication, can't control usage of UI key directly from API.To make sure we have more secured UI call, we have implemented custom logic which can be used for any javascript applicationReferenceThis helped me to at least distinguish UI calling API and API directly called from other application/tools like postman.Thanks all for your help.
Generate Pgp Key Pair
- If the key generation was successful, you should be offered with the following options.
- Click on 'Finish' to finish the process
Setting an Expiry Date on the Key-pair
Now we move forward with setting an expiry date on the keys. It is a good practice because if your key is compromised without your knowledge, the expiry date will limit the lifetime of your public and private keys.
- Open Kleopatra again
- Right-click on your PGP key-pair and select 'Change Expiry Date..'
- Set 2 Years as the expiry period then click 'OK'
- Expiry date should be set
Backing up the PGP Key-pair
It is important to create a backup of the keys. It ensures that you can restore the key-pair and access the previously encrypted emails in case your computer is destroyed or gets stolen.
- Right-click on the key-pair and select 'Export Secret Keys..'
- Enter a filename and path for the backup. Tick the 'ASCII armor' box.
- If everything did go well, the backup secret key should be saved into a file.
Now back up the public key
- Right-click on the key-pair and select 'Export Certificates ..'
Now take both files (public and the private key) and copy them to an offsite location. It can be an external USB drive, a Dropbox folder or you can even print it out on a piece of paper!
Generate Pgp Key Windows
It is safe to store the private key elsewhere, because the private key is encrypted as we set a strong passphrase on it earlier. In other words, the secret key cannot be retrieved without entering the passphrase first.
