Export non-exportable Certificate in Microsoft Windows

Did you forgot to mark this CheckBox during Certificate Import?

Luckily iSECPartners has created a Jailbreak software for this task.

Software: https://github.com/iSECPartners/jailbreak

...\jailbreak-master\binaries>jbstore64.bat -s "SYSTEM" -o outputFileName.pfx -n "certificateName" -p "password"

Default password for exported certificate (if not provided as -p parameter): "password"
