The procedures of the use of “uid” and the “Key ID” for deleting the non-public and public keys shall be equipped as smartly. So, let’s get started!

Type of GPG keys

The GPG key pair accommodates two kinds of keys: Private and Public keys. You can use the general public key for the information encryption, and that encrypted knowledge shall be decrypted the use of the Private key.

In the below-given output, “pub” represents Public key, “uid” signifies the “User ID”, and “sub” displays the Subkey:

The secret keyring shops the non-public GPG keys, and to record them at the Linux terminal, upload the “–list-secret-keys” within the “gpg” command and execute it:

Here, “sec” represents Secret or Private key, “uid” is for the User ID, and “ssb” signifies the Secret Subkey:

Note: To delete the GPG keys of a selected consumer, be aware down its consumer ID “uid” and “Key ID” from the output of the above-given instructions after which transfer to the following segment.

How to delete GPG keys of a unmarried consumer in Linux

There are two strategies for deleting a consumer’s private and non-private GPG keys; both you’ll be able to delete them the use of the consumer ID “uid” or their Key ID (Public ID). Also, understand that you must delete the non-public key first after which transfer against the general public key deletion procedure, as GPG simplest allows you to delete the general public key when its similar non-public secret’s got rid of from the machine.

Here is the syntax for deleting non-public GPG the use of the “uid”:

For example, to delete the GPG keys of the consumer “Liza”, we can first delete its non-public key by way of specifying the “Liza” “uid” within the following command:

A affirmation conversation field will seem to your display screen, click on at the “Delete Key” button, and the non-public key of the desired consumer shall be deleted inside of a couple of seconds:

Now, take a look at the syntax for deleting the general public GPG of the consumer by way of the use of its “uid”:

To delete the non-public of the “Liza”, we can write out the next command within the terminal:

Enter “y” to substantiate the deletion procedure, and you’re all completed!

Next, record out the private and non-private keys for the verification goal:

Now, we can exhibit the GPG key deletion means the use of a consumer’s Key ID. To delete a consumer’s non-public GPG key, we can practice the below-given syntax:

For example, to delete the non-public GPG key of “john”, we can upload its Key ID within the “gpg” command within the following method:

Click at the “Delete key” button to substantiate that you need to delete the name of the game key of the discussed consumer completely:

The error-free output signifies that John’s non-public secret’s deleted. Now, to delete the general public key, we can execute the “gpg –delete-key” command with its Key ID:

Check out the record of private and non-private keys to substantiate whether or not the deletion operation labored or no longer:

How to delete GPG keys of more than one customers in Linux

The “gpg” command additionally allows you to delete the GPG keys of more than one customers without delay, and it follows the order for the deletion through which the uids or the Key IDs are added.

Before transferring against, we can record out the non-public and public GPG keys and be aware down the uid, the non-public and Key ID of the “sharqa” and “fred” consumer:

Using the Linux terminal, you’ll be able to delete the GPG keys of the more than one customers by way of including their uids within the gpg command:

For example, we can execute the next command for deleting non-public keys of “sharqa” and “fred” with the assistance of their “uids”:

The gpg command will originally delete the name of the game key of the consumer “sharqa,” after which it’ll take away the fred’s key from the name of the game keyring:

Lastly, we can delete the general public keys as smartly:

Similarly, if you wish to delete the non-public GPG key of more than one customers by way of the use of their Key IDs, then take a look on the below-given syntax:

For example, to delete the non-public GPG key of “sharqa” and “fred”, we can upload their Key IDs within the following method:

Note that we’ve got added the Key ID of the “sharqa” first; that’s why its non-public secret’s going to delete ahead of fred’s:

Now, hit the “Delete Key” button for the affirmation:

At this level, the non-public key of the consumer “sharqa” is deleted, and the gpg command will transfer against the deletion of fred’s key:

The above-given error-free output signifies that the non-public keys of each customers are actually deleted. In your next step, we can write the next command for deleting the sharqa’s and fred’s public keys from the general public keyring:
