It allows for easy filtering of certificates based on the days until expiration. It\u0027s use is reminiscent of the `grep` utility.\n\nIt can produce [Test Anything Protocol](http://testanything.org/) which makes this tool useful as part of test suites that deal with TLS certificate expiration.\n\n## Examples\n\nErrors are sent to `STDERR`, the listing of certificates that satisfy the given criteria is sent to `STDOUT` but can be suppressed by using `--quiet` in the command line. TAP output is triggered by the `--tap` command line option.\n\n### TAP \u2014 Test Anything Protocol \u2014 support\n\nTAP-formatted test results provide output that can be captured by more elaborate test suites:\n\n```\n$ ccheck --input-file certificate.list --tap --num-workers 6\n1..0\nnot ok 1 - losmunoz.com:443 x509: certificate is valid for *.athena.pics, athena.pics, not losmunoz.com TLS\nok 2 - libertad.link:443 expires in 59 days (took 0.384 secs) TLS\nok 3 - esmtp.email:443 expires in 59 days (took 0.384 secs) TLS\nok 4 - lem.click:443 expires in 64 days (took 0.384 secs) TLS\nok 5 - lem.link:443 expires in 64 days (took 0.384 secs) TLS\nok 6 - quad.click:443 expires in 70 days (took 0.384 secs) TLS\nok 7 - google.com:443 expires in 58 days (took 0.181 secs) TLS\nnot ok 8 - cert/google-chain.pem certificate is expired TLS\nok 9 - allaboutworms.com:443 expires in 39 days (took 0.291 secs) TLS\nok 10 - outlook.com:443 expires in 414 days (took 0.249 secs) TLS\nok 11 - tupsiquiatra.expert:443 expires in 59 days (took 0.276 secs) TLS\nok 12 - isipp.com:443 expir",
