keyart - Create ASCII art of an OpenPGP key.


keyart [-c|--color] [-l|--longid] [-f|--fingerprint HEX [-f|--fingerprint HEX ...]]
[-k|--keyring KEYRING [-k|--keyring KEYRING ...]] [KEYID ...]


keyart creates an ASCII art representation of public OpenPGP keys. The art is an
implementation of the Drunken Bishop by Dirk Loss. Documentation about the algorithm can
be found in /usr/share/doc/signing-party/keyart/, or as appropriate for your distribution.

keyart supports printing the ASCII art in both plain text (default) and ANSI color. ANSI
color uses a "heat map", where cold (blue) represents squares in the room the drunk bishop
has rarely visited, and hot (red) represents squares in the room the drunk bishop has
frequently visited. There is a 1:1 ratio of color to printed character.

The KEYIDs are key identifiers (fingerprint, keyid, user ID, etc. see gpg(1) for
details). If no KEYID is given, keyart creates an ASCII art representation for all keys


-c | --color
Print the ASCII art using ANSI color to the terminal.

-l | --longid
Print the 16-character long ID of a on OpenPGP key in the footer badge. Default is
to print the 8-character short ID. Silently ignored if "-f | --fingerprint HEX" is

-f | --fingerprint HEX
Any arbitrary hexadecimal string of any length. Could be an MD5, SHA1, SHA2, or
SHA3 hexadecimal checksum. Useful for comparing and analyzing potential collisions
with existing keys. This option can be repeated multiple times.

-k | --keyring KEYRING
An OpenPGP public key file or keyring, from which the KEYIDs are to be found. If
this option is not present, the KEYIDs are found from GnuPG's default keyring
(usually ~/.gnupg/pubring.gpg); if it is repeated multiple times, the provided
KEYRINGs are used as successive sources.

-h | --help
Print the help message and quit.


HOME Set the default home directory.

Set the gpg binary. Default: "gpg".

Set the default working directory for gpg. Default: "~/.gnupg".


0 keyart was executed successfully.

1 gpg(1) or gpg2(1) are not installed.

2 The supplied hexadecimal string is not a multiple of 8 bytes.
