Create a GPG master key
Introduction
A master key can technically be used to sign without a need for a subkey. However, we recommend that you only use the master key (sometimes called “certification key”) to certify and create subkeys.
You can generate a master and subkey from DigiCert® Software Trust Manager or our command line interface SMCTL.
A GPG master key contains:
RSA, ECDSA, or EdDSA keypair
User IDs (UIDs)
Self-signature for every UID associated with the master key
Key that can certify
The master key can be used to:
Add or revoke subkeys
Add, change, or revoke user identities (UIDs) associated with the key
Add or change the expiration date on itself or any subkey
Sign other people's keys for web-of-trust purposes

What is a User ID (UID)?
UIDs are assigned to the master key. They are used to identify your GPG key.
UID format
Name (Comment) <email>
UID examples
John Doe (Signing) john.doe@example.com
Jane Doe jane.doe@example.com
Tip
UIDs are shown in some GnuPG operations. Select a name, email address, and comment that are both professional and commonly used for PGP-protected communication, for example your company email address or one you use for signing off on project commits.
