Ultimate-GPG-Settings

## ABOUT
The Goals of this Gist are to:
[1] Increase the GnuPG key size limit beyond 4096 bits.
[2] Provide configuration files that maximize security and anonymity.

For now, the ideal configuration files have been provided.
The Debian_Linux_GnuPG_Compiler.bash script works to build GnuPG with the 4096 bit key size limit raised.

Please provide input. Feedback and changes welcome.

##NOTES##
#Read Linux manuals and the GnuPG Options Index to understand these options and apply judgement to change them as needed.
#Use the latest Linux CLI implementation as the default GPG application. Create backups before experimentation.
#
#Create the default directories and .conf files with --version or --gpgconf-test or --list-config.
#Check for reasons behind errors via --debug-all --debug-level guru.
#Always copy this .conf file and all other related files into the ~/.gnupg folder.
#Check results with --list-packets, --check-sigs, --list-keys, --list-chain, or use --dry-run.
#
#A list of cross-platform and widely-supported algorithms is on the GnuPG website. Only the most widely-supported algorithms are mentioned in this .conf file.
#Compiling GPG with a different or newer libgcrypt may allow access to other different algorithms inside libgcrypt.
#
#Always run this command on the GnuPG directory to ensure proper ownership and permissions: "sudo chmod -R 700 ~/.gnupg && sudo chown -R $USER:$GROUP ~/.gnupg".
#General Warning 1: Avoid metadata leaks.
#General Warning 2: Manually change system-time, use tools that spoof system-time, or use faked-system-time before generating keys.
#General Warning 3: When generating keys, set the Master Key to (C)ERTIFY only, and similarly, give only one flag (E, S, A) to each of the subkeys.

	The Goals of this Gist are to:
	[1] Increase the GnuPG key size limit beyond 4096 bits.
	[2] Provide configuration files that maximize security and anonymity.

	For now, the ideal configuration files have been provided.
	The Debian_Linux_GnuPG_Compiler.bash script works to build GnuPG with the 4096 bit key size limit raised.

	Please provide input. Feedback and changes welcome.

	#throw-keyids is similar to the --hidden-recipient option but works on all keyids at once. It blocks GnuPG from emitting the keyid on an encrypted packet.
	#This makes it difficult but not impossible for someone to deduct the properties of the public-key being used to encrypt a file. Keep changing the public-key to guarantee high secrecy.
	#The throw-keyids option does not work on signatures and GnuPG does not hide the keyid in a standalone signature.
	#One can Encrypt and Sign together to hide the signature packet under the encryption packet.
