installation
go install github.com/jimmypw/ckcert
Usage
To check minimum remaining days
./ckcert -f "path to certificate" -d "minimum days"
e.g.
./ckcert -f /tmp/cert.crt -d 100
This would make sure there are at least 100 days remaining on the certificate
To check minimum remaining percentage
./ckcert -f "path to certificate" -p "percentage of validity"
e.g.
./ckcert -f /tmp/cert.crt -p 30
This will ensure that there is at least 30% of the life of the certificate remaining.
