--store

Create a PGP message packet (RFC 1991). This does not

encrypt data; it just puts it into the right packet format.

Decryption Commands

--decrypt [file]

Decrypt a file. If no file is specified, stdin is decrypted.

Decrypted data is sent to stdout or to the file specified with

the --output flag. If the encrypted data is signed, the signature

is also verified.

--decrypt-files [files]

Decrypt files one after another, either at the command line or

sent to stdin one per line.

Other Commands

--check-trustdb

Check the list of keys with defined trust levels to see if they

have expired or been revoked.

--export-ownertrust

Create a backup of the trust values for keys.

--h, --help

Display a help message.

--import-ownertrust [file]

Import trust values from a file or stdin. Overwrites existing

values.

--list-packets

Display packet sequence for an encrypted message. Used for

debugging.

--update-trustdb

Update the database of trusted keys. For each key that has no

defined level of trust, --update-trustdb prompts for an esti-

mate of how much the key’s owner can be trusted to certify

other keys. This builds a web of more-trusted and less-trusted

keys by which the overall security of a given key can be

estimated.

--version

Display version information and quit.

--warranty

Display warranty ...
