Public and private keys are used in asymmetric encryption to encrypt and decode messages. This allows you to send or publish your public key over an open insecure network. ..

Your public key is used to encrypt a message by the party trying to send you a secure message. You receive the message and use your private key to decrypt it after receiving it. You can then securely encrypt communications with the sender using the sender’s public key. They then decrypt the messages you have encrypted using your private key.

steps to go back Up and restore GPG keys on Linux

Backup GPG key

gpg –export-secret-key

gpg –keyserver hkp://www.ubuntu.com –recv-keys ECDSA 2048-bit Step 3: Save the new key to your keyring. gpg –export-key ECDSA “Your GPG Key”

Step 3: You can see in the output above that the user uses the name “risan.” ..

The command output shows that the user has a public key with the serial number D020LB50C994521EB6E9EEE932B805973FE94CAC and a UID of [ultimate]. ..

Export the key in ASCII format using the “O” option if you don’t want to export the key in binary format. ..

gpg –export-secret-key ..

Restore GPG Key

gpg –import-key Step 2: After you have imported your GPG key, you can use it to sign documents. To do this, you will need to create a new keypair and add it to your GPG keyring.

gpg –trust-databaserun Step 3: After restoring your GPG trust databaserun, you will need to re-enable the keyring.

gpg –edit-key and change the trust level to the one you want. ..

Final Words

GPG is a public key encryption system that was created as a result of using the standard. It is used to encrypt and decrypt files. Two keys are actually used, a public key and a private key. A public key and a private key are shared by everyone. As the name implies, private keys are not shared or given to third parties. Public key sharing can be done securely. In fact, for the system to work, public keys must be shared.
