![]() Revocation certificates are automatically generated for newly created keys in ~/.gnupg/openpgp-revocs.d/. To avoid this, use the full fingerprint or long key ID, when receiving a key. Warning: using a short key-id may encounter collisions. Long Key-ID is the last 16 characters of the fingerprint. In some contexts this value needs to have 0x prepended ( 0x123456AB). Short Key-ID is the last 8 characters of the fingerprint. There’s also a short key-id and long key-id. When validating keys for key signing, the fingerprint is used. The key-id defines a 160-bit fingerprint for a key, which is typically expressed as a hexadecimal string, divided into 10 4-character groups.If you want to use the key certificate with more than one email account, multiple user IDs would be needed. The key certificate can have more than one user ID. The gpg program store it in RFC2822 format ( John Doe ). The user-id defines a name/e-mail address that is associated with the key certificate.GnuPG also provides support for S/MIME and Secure Shell ( ssh). A wealth of frontend applications and libraries are available. GnuPG, also known as GPG, is a command line tool with features for easy integration with other applications. ![]() GnuPG allows you to encrypt and sign your data and communications it features a versatile key management system, along with access modules for all kinds of public key directories. GnuPG ( gpg) is a complete and free implementation of the OpenPGP standard as defined by RFC4880 (also known as PGP).
