PGP Command Summary:

Encrypting	-e(encrypt) -s(sign) -t(text) -a(ascii) -c(conventional)
`pgp -e messagefile her_user_id`	Encrypt email w/ her_key
`pgp -c filename`	Conventional encryption, for my system only
`pgp -es messagefile her_user_id -u your_user_id`	Encrypt & Sign w/ one or multiple public_keys
`pgp -e messagefile user_id1 user_id2 user_id3 . . .`	Encrypt w/ multiple public_keys
`pgp -ca filename`	Conventional encryption into ASCII file for email
`pgp -cw filename`	Conventional encryption, wipe original file afterwards
`pgp -ew messagefile her_user_id`	Encrypt & wipe message w/ her public_key
`pgp -eat message her_user_id`	Encrypt into ASCII textfile using one or more IDs
`pgp -eatf her_user_id`	Filter: reads from keyboard input

Signatures	Meaning:
`pgp -s messagefile -u your_user_id`	Sign: uses your secret key to create digital signature
`pgp -sta messagefile user_id -u your_user_id`	Sign, Text, ASCII: creates ASCII text file for emailing
`pgp -sb messagefile user_id -u your_user_id`	Sign By Itself: creates detached sig. certificate in file
`pgp -se messagefile user_id -u your_user_id`	Sign & Encrypt
`pgp -sea messagefile user_id -u your_user_id`	Sign & Encrypt using ASCII output
`pgp -seaw messagefile user_id -u your_user_id`	Sign & Encrypt w/ ASCII & Wipe afterwards
`pgp -seat messagefile user_id -u your_user_id`	Sign, Encrypt w/ ASCII & Text output file

Miscellaneous Switch Options (used together with other switches)	Meaning:
`-a`	ASCII Armor--all output is ASCII Radix 64
`-f`	Filter: reads file from standard input (keyboard)
`-m`	More: displays decrypted file on screen but doesn't save file; when encrypting tells recipient to not save file.
`-o outputfile`	Output: says what to name outputfile
`-p encryptedfile`	Preserve: keeps the original filename plaintext
`-t`	Text:: treats all input and output as text files
`-w`	Wipe: writes over original file so can't be "undeleted"

Decrypting & Authenticating -o(output)	Meaning:
`pgp ciphertextfile -o plaintextfile`	Decrypts file to specified output filename
`pgp signedfile -o plaintextfile`	Authenticates signature with public keys on your pubring
`pgp -m ciphertextfile`	More: doesn't save decrypted file to disk

Key Management	-k(key) -g(generate) -a(add) -x(extract) -v(view) -c(certify) -e(edit) -r(remove) -s(sign or signature) -d(delete or revoke or disable)
`pgp -kg`	Keypair Generate: creates new public and secret keys
`pgp -ke userid keyring` (for user_id or passphrase or trust parameters)	Keyring Edit: requires passphrase to edit trust or IDs
`pgp -ka keyfile keyring`	Key Add: updates keyring with contents of keyfile
`pgp -kaf keyfile keyring`	Key Add Filter: updates as above but from standard input
`pgp -kx` [or -kxa] `user_id keyfile keyring`	Key Extract [ASCII]: copies ID's key to keyfile from keyring
`pgp -kxaf user_id keyfile keyring`	Key Extract ASCII Filter: same as above but from std input
`pgp -kv[v] [userid] keyring`	Keyring View [Verbose]: shows key[s] & signature[s]
`pgp -kvc [userid] keyring`	Keyring View & Check: displays key[s] & fingerprint[s]
`pgp -kc [userid] keyring`	Key Check: Checks user_id's key on keyring w/ signature
`pgp -kr userid keyring`	Key Remove: revokes user_id's key on keyring
`pgp -ks her_userid -u your_userid keyring`	Key Sign: Signs her_key with your secret_key on keyring
`pgp -krs userid keyring`	Key Remove Signature: deletes your sig from user_id's key
`pgp -kd your_userid`	Key Disable: Revokes or disables your_user_id
`pgp -kd userid`	Key Disable: Revokes or disables user_id's public key

Esoteric & Combination Commands (Reviewed)	Meaning:
`pgp -d ciphertext`	Decrypt & Leave Signature Intact
`pgp -sb textfile -u your_userid`	Sign By Itself: creates sig. certif. in a file by itself
`pgp -b ciphertextfile`	Detach a signature from a signed message into a file
`pgp -sea textfile her_userid`	Sign Encrypt ASCII
`pgp -kxa userid keyfile keyring`	Key Extract into ASCII file
`pgp -sea message her_userid`	Sign Encrypt to ASCII file
`pgp -seat message her_userid`	Sign Encrypt ASCII & Text file
`pgp -m ciphertextfile`	Decrypt & display on screen but don't save to file
`pgp -steam message.txt her_userid`	Sign Text Encrypt ASCII More: does it all
`pgp -p ciphertextfile`	Preserve: restores file to original filename before encryption
`pgp -feast her_userid outputfile`	Filter Mode, Encrypt, ASCII, Sign Text using std input
`pgp -seaw message her_useid`	Sign & Encrypt w/ ASCII & Wipe afterwards
