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.
