KEY GENERATION

	Generate a private key:
		NAME="Test User"
		EMAIL="test@user.example"
		echo -e "Key-Type:RSA\nKey-Length:4096\nSubkey-Type:RSA\nSubkey-Length:4096\nExpire-Date:0\nName-Real:$NAME\nName-Email:$EMAIL" | gpg --batch --gen-key
		gpg --edit-key $EMAIL
		  gpg> setpref SHA512 SHA384 SHA256 SHA224 AES256 AES192 AES CAST5 ZLIB BZIP2 ZIP Uncompressed
		  Set preference list to:
		       Cipher: AES256, AES192, AES, CAST5, 3DES
		       Digest: SHA512, SHA384, SHA256, SHA224, SHA1
		       Compression: ZLIB, BZIP2, ZIP, Uncompressed
		       Features: MDC, Keyserver no-modify
		  Really update the preferences? (y/N) y
		  gpg> passwd
		  This key is not protected.
		  Enter the new passphrase for this secret key.
                  gpg> save

	Add email to key:
		gpg --edit-key <key-id>
		  gpg> adduid
		  Real Name: <name>
		  Email address: <email>
		  Comment: <comment or Return to none>
		  Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? O
		  Enter passphrase: <password>
		  gpg> uid <email>
		  gpg> trust
		  Your decision? 5
		  Do you really want to set this key to ultimate trust? (y/N) y
		  gpg> setpref SHA512 SHA384 SHA256 SHA224 AES256 AES192 AES CAST5 ZLIB BZIP2 ZIP Uncompressed
                  Set preference list to:
                       Cipher: AES256, AES192, AES, CAST5, 3DES
                       Digest: SHA512, SHA384, SHA256, SHA224, SHA1
                       Compression: ZLIB, BZIP2, ZIP, Uncompressed
                       Features: MDC, Keyserver no-modify
                  Really update the preferences? (y/N) y
		  gpg> save

	Generate an ASCII version of your public key:
		gpg -a --output pubkey.txt --export '<KEY NAME>'

	Generate an ASCII version of your private key:
		gpg -a --output seckey.txt --export-secret-key '<KEY NAME>'
	
	Optional: Register your key with public keyserver:
		gpg --keyserver pgp.mit.edu --send-keys 'Your Name'

	
KEY IMPORT

	Import from a file:
		gpg --import key.asc
	
	Import from keyserver:
		gpg --keyserver pgp.mit.edu --search-keys 'myfriend@his.isp.com'
	

ENCRYPTION

	Encryption:
		gpg -e -r Name foo.txt
	
	Decryption:
		gpg --output foo.txt -d foo.txt.gpg

	
SIGNATURES

	Create signature:
		gpg -a --detach-sign your-file.zip

	Check signature:
		gpg --verify crucial.tar.gz.asc crucial.tar.gz
	
	
KEY MANAGEMENT

	List all imported public keys:
		gpg --list-public-keys

	List all imported secret keys:
		gpg --list-secret-keys

	Remove public key:
		gpg --delete-key 'myfriend@his.isp.example'

	Remove secret key:
		gpg --delete-secret-key 'me@home.example'
	
	Change passphrase of key:
		gpg --edit-key 'me@home.example' passwd
		gpg> save
	
	Export public key:
		gpg --armor --output 'myfriend.gpg' --export 'myfriend@his.isp.example'

	Export secret key:
		gpg --armor --output 'me.gpg' --export-secret-key 'me@home.example'
