Signing commits

I am using app called SmartGit and manual says

if you are using Windows, please install Gpg4win (verified with Gpg4win 3.1.16)
run gpa.exe (usually found in C:\Program Files (x86)\Gpg4win\bin) and create a key pair securing it with a passphrase
in SmartGit Repository | Settings, tab Signing configure the full path to the gpg.exe and enter the Key ID of your created key pair
if necessary, select Sign all commits
when committing a file or tagging, a popup of GPG will occur and ask you for the key's passphrase (actually just the first time in the app's lifetime)

run gpg --full-generate-key to generate key pair
run gpg --list-secret-keys --keyid-format=long to get key ID
run gpg --armor --export $USE_ID_YOU_GET to get public key to copy into GitHub profile settings
