dotnet-ssllabs-check Nuget

Tool that will check ssllabs score api and cert expiration when provided a list of hosts.


This is an Unofficial tool, using the SSL Labs API v3. See the SSL Labs terms of use. This tool works by sending assessment requests to remote SSL Labs servers and that information will be shared with SSL Labs.


dotnet tool install --global dotnet-ssllabs-check



Unofficial SSL Labs Client

Usage: ssllabs-check [options] <hostname(s)>

  hostname(s)              Hostnames to check SSL Grades and Validity

  -?|-h|--help             Show help information
  -v|--version             Show version and service information
  -o|--output <DIRECTORY>  Output directory for json data [Default: does not write out data]
  --hostfile <PATH>        Retreive list of hostnames from file to check (one host per line, # preceding comments)
  --emoji                  Show emoji when outputing to console


  • Clearly displays time to expiration for leaf certificates (if RSA and EC are both served then both are listed).
  • Highlights expiring certificates if 90 Days, if original certificate validatity period is 90 days or under (Let's Encrypt) then uses 30 days.
  • Shows SSL Grade per Host and IP address combo.
  • Error Codes types are combined for exit code with bitwise or.
  • Runs requests in parallel when under api limits, but writes to console in order of scan finishing first.
