Helper script to ease generating GPG keys.

• Debian-based systems:

apt-get install gnupg

• MacOS X:

brew install gnupg

Just run:

bash ./gen-key.sh

and answear couple of questions. If you are using GnuPG classic version (1.4) after successful run you should have two files in dir:

• rsa-4096.pub - public key
• rsa-4096.sec - private key

If you answear Y to export, you should also have (applicable to classic and modern GnuPG versions):

• public.key.asc - public key in ASCII format

(Linux-only)

If GnuPG complains about small entropy, you can check its "quality":

cat /proc/sys/kernel/random/entropy_avail

If it returns anything less than 100-200, you have a problem. You can solve that by installing haveged - a simple entropy daemon.

apt-get install haveged
