    Here's a quick summary of PGP v2.6 commands.

    To encrypt a plaintext file with the recipient's public key:
	 pgp -e textfile her_userid

    To sign a plaintext file with your secret key:
	 pgp -s textfile [-u your_userid]

    To sign a plaintext file with your secret key, and then encrypt it 
    with the recipient's public key:
	 pgp -es textfile her_userid [-u your_userid]

    To encrypt a plaintext file with just conventional cryptography, type:
	 pgp -c textfile

    To decrypt an encrypted file, or to check the signature integrity of a
    signed file:
	 pgp ciphertextfile [-o plaintextfile]

    To encrypt a message for any number of multiple recipients:
	 pgp -e textfile userid1 userid2 userid3

    --- Key management commands:

    To generate your own unique public/secret key pair:
	 pgp -kg

    To add a public or secret key file's contents to your public or
    secret key ring:
	 pgp -ka keyfile [keyring]

    To extract (copy) a key from your public or secret key ring:
	 pgp -kx userid keyfile [keyring]
    or:  pgp -kxa userid keyfile [keyring]

    To view the contents of your public key ring:
	 pgp -kv[v] [userid] [keyring] 

    To view the "fingerprint" of a public key, to help verify it over 
    the telephone with its owner:
	 pgp -kvc [userid] [keyring]

    To view the contents and check the certifying signatures of your 
    public key ring:
	 pgp -kc [userid] [keyring] 

    To edit the userid or pass phrase for your secret key:
	 pgp -ke userid [keyring]

    To edit the trust parameters for a public key:
	 pgp -ke userid [keyring]

    To remove a key or just a userid from your public key ring:
	 pgp -kr userid [keyring]

    To sign and certify someone else's public key on your public key ring:
	 pgp -ks her_userid [-u your_userid] [keyring]

    To remove selected signatures from a userid on a keyring:
	 pgp -krs userid [keyring]

    To permanently revoke your own key, issuing a key compromise 
    certificate:
	 pgp -kd your_userid

    To disable or reenable a public key on your own public key ring:
	 pgp -kd userid

    --- Esoteric commands:

    To decrypt a message and leave the signature on it intact:
	 pgp -d ciphertextfile

    To create a signature certificate that is detached from the document:
	 pgp -sb textfile [-u your_userid]

    To detach a signature certificate from a signed message:
	 pgp -b ciphertextfile

    --- Command options that can be used in combination with other 
	command options (sometimes even spelling interesting words!):

    To produce a ciphertext file in ASCII radix-64 format, just add the
    -a option when encrypting or signing a message or extracting a key:
	 pgp -sea textfile her_userid
    or:  pgp -kxa userid keyfile [keyring]

    To wipe out the plaintext file after producing the ciphertext file,
    just add the -w (wipe) option when encrypting or signing a message:
	 pgp -sew message.txt her_userid

    To specify that a plaintext file contains ASCII text, not binary, and
    should be converted to recipient's local text line conventions, add
    the -t (text) option to other options:
	 pgp -seat message.txt her_userid

    To view the decrypted plaintext output on your screen (like the
    Unix-style "more" command), without writing it to a file, use 
    the -m (more) option while decrypting:
	 pgp -m ciphertextfile

    To specify that the recipient's decrypted plaintext will be shown
    ONLY on her screen and cannot be saved to disk, add the -m option:
	 pgp -steam message.txt her_userid

    To recover the original plaintext filename while decrypting, add 
    the -p option:
	 pgp -p ciphertextfile

    To use a Unix-style filter mode, reading from standard input and
    writing to standard output, add the -f option:
	 pgp -feast her_userid <inputfile >outputfile
