Can a master key be used for a subkey?
The master key is used for other keys, creating subkeys and subkeys. Your master key must be kept very safe. Signatures of trust are also collected on your master key. If the master key is compromised, you have no choice but to revoke it and all the subkeys attached to it.
Can a subkey be signed by the same person?
They all associate to their primary key, so anything signed by any subkey can be associated with the main key and can hence be considered to be signed by the same person. There are a number of advantages to employing the approach documented here to managing your GPG key.
Are there any advantages to storing the primary secret key offline?
Another advantage to the approach detailed in this article is that storing the primary secret key on offline removable media means that it is impossible for a system or device compromise to result in a compromise of the primary secret key. Of course, the media containing the primary secret key would need to be properly protected.
When do you create an OpenPGP key you create two subkeys?
When you create an OpenPGP key with GPG (which is the focus of this article), you create two subkeys by default: one for encryption and one for signing. The subkeys discussed in this article are only used for signing. The reason for this is that it is impossible to sensibly employ multiple encryption subkeys.
When do you create a new public encryption key?
Whenever you create a new public encryption key, a keypair is generated instead of a single key. This keypair consists of a main key, also called the master key and a subkey. A master key can be used to create additional subkeys that are then bound to it.
How to delete registry key with subkeys Win32?
To test this example, create the following registry key by using Regedt32.exe, and then add a few values and subkeys: After running the code, use the F5 key to refresh the registry data, and notice that the TestDir key is deleted.
What to do if your master key is compromised?
If the master key is compromised, you have no choice but to revoke it and all the subkeys attached to it. The default subkey is used for encryption and decryption of messages. Additional subkeys can be created for signing.
