At a later stage, if necessary, the expiration date can be extended without having to re-issue a new key. This way even if access is lost to the keyring, it will allow others to know that it is no longer valid.

An expiration date: a period of one year is good enough for the average user.

A larger keysize of 4096 "gives us almost nothing, while costing us quite a lot" (see why doesn’t GnuPG default to using RSA-4096).

The default RSA and RSA for sign and encrypt keys.

The command will prompt for answers to several questions. Generate a key pair by typing in a terminal:Īlso add the -expert option to the command line to access more ciphers and in particular the newer ECC cipher ( Wikipedia:Elliptic-curve cryptography). To show the master secret key for example, run gpg -list-secret-keys -keyid-format=long user-id, the key-id is the hexadecimal hash provided on the same line as sec.

Whenever a key-id is needed, it can be found adding the -keyid-format=long flag to the command.

Whenever a user-id is required in a command, it can be specified with your key ID, fingerprint, a part of your name or email address, etc.

Users with existing GnuPG home directory are simply skipped. This will add the respective /home/user1/.gnupg/ and /home/user2/.gnupg/ and copy the files from the skeleton directory to it. There is also a simple script called addgnupghome which you can use to create new GnuPG home directories for existing users: When the new user is added in system, files from here will be copied to its GnuPG home directory. If you want to setup some default options for new users, put configuration files in /etc/skel/.gnupg/. Gnupg_home/gpg.conf (or /etc/gnupg/gpg.conf) no-default-keyringĪdditionally, pacman uses a different set of configuration files for package signature verification. For example, to make GnuPG always use a keyring at a specific path, as if it was invoked as gpg -no-default-keyring -keyring keyring-path. Do not write the two dashes, but simply the name of the option and required arguments.

See the GnuPG manual for a comprehensive list.Ĭreate the desired file(s), and set their permissions to 600 as discussed in #Home directory.Īdd to these files any long options you want. These two configuration files cover the common usecases, but there are more auxiliary programs in the GnuPG suite with their own options. See Dirmngr Options for possible options. dirmngr is a program internally invoked by gpg to access PGP keyservers. dirmngr checks gnupg_home/nf and /etc/gnupg/nf.Since gpg is the main entrypoint for GnuPG, most configuration of interest will be here. gpg checks gnupg_home/gpg.conf (user) and /etc/gnupg/gpg.conf (global).For arguments you would like to be the default, you can add them to the respective configuration file: In case this directory or any file inside it does not follow this security measure, you will get warnings about unsafe file and home directory permissions.Īll of GnuPG's behavior is configurable via command line arguments. This is for security purposes and should not be changed. Only the owner of the directory has permission to read, write, and access the files. īy default, the home directory has its permissions set to 700 and the files it contains have their permissions set to 600. Set the $GNUPGHOME environment variable.The GnuPG home directory is where the GnuPG suite stores its keyrings and private keys, and reads configurations from. If you want to use a graphical frontend or program that integrates with GnuPG, see List of applications/Security#Encryption, signing, steganography. The shell script /usr/bin/pinentry determines which pinentry dialog is used, in the order described at #pinentry.

This will also install pinentry, a collection of simple PIN or passphrase entry dialogs which GnuPG uses for passphrase entry. 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.
