Lists your keys along with any signatures they have. Lists all keys from the public keyrings or those specified.
Lists all keys from the keyrings or those specified. The signature can be either contained with the file or be a separate detached signature file. If the decrypted file is signed, the signature is verified. May be combined with -sign.ĭecrypts file (or stdin if no file is specified) and writes it to stdout (or the file specified with -output). May be combined with -encrypt.Įncrypts data. gnugpg directory will also hold encryption files such as secring.gpg for your secret keys (secret keyring), pubring.gpg for your public keys (public keyring), and trustdb.gpg, which is a database for trusted keys. Helpful options include keyserver entries. You can use a different options file and specify it with the -options parameter when invoking gpg. You can edit this file and uncomment or change any default options you want implemented for GPG. gnugpg/options file contains commented default options for GPG operations (changed to. gnugpg directory is created in your home directory with a file named options. Some commands and options have a short form that uses only one hyphen. Commonly used commands and options are listed in Table 16-1. GNU Privacy Guard (GPG) operations are carried out with the gpg command, which uses both commands and options to perform tasks. On KMail, you can select the encryption to use on the Security panel in the Options window. On Evolution, you can select PGP encryption and signatures from the Security menu to use GnuPG (the PGP options use GnuPG on CentOS Linux). Currently, Evolution and KMail both support GnuPG encryption and authentication. With GnuPG, you can both encrypt your messages and digitally sign them-protecting the message and authenticating that it is from you.
GnuPG is GNU open source software that works much like Pretty Good Privacy (PGP) encryption. To protect messages that you send by e-mail, most Linux distributions provide GNU Privacy Guard (GnuPG) encryption and authentication.
