-# x509-info
-
-At this point it's pretty clear that I'll never remember the syntax for `openssl` to show various information about a certificate. At last I will not have to google for that syntax ever again.
-
-## Usage
-
-``` shell
-Usage:
-    x509-info [DOMAIN]
-    x509-info (-f long) [DOMAIN]
-
-Options:
-    -f, --format      Format the result. Valid values: short, long. Default: short
-    -i, --insecure    Skip the TLS validation. Default: false
-    -p, --port        Specify the port. Default: 443
-    -v, --version     Print version information
-    -h, --help        Print this message
-```
-
-The default format will print a short message:
-``` shell
-$ ./bin/x509-info github.com
-github.com, valid until Thu, 14 Mar 2024 23:59:59 UTC (86 days left)
-```
-
-It's possible to get more details:
-``` shell
-$ ./bin/x509-info -f long github.com
-certificate
-  version: 3
-  serial: 17034156255497985825694118641198758684
-  subject: github.com
-  issuer: DigiCert TLS Hybrid ECC SHA384 2020 CA1
-
-validity:
-  not before: Tue, 14 Feb 2023 00:00:00 UTC
-  not after: Thu, 14 Mar 2024 23:59:59 UTC
-  validity days: 394
-  remaining days: 86
-
-SANs:
-  • github.com
-  • www.github.com
-```
-
-You can also check expired certificates:
-``` shell
-$ ./bin/x509-info -i expired.badssl.com
-*.badssl.com, not valid since Sun, 12 Apr 2015 23:59:59 UTC (expired 3172 days ago)
-```
-
-## Notes
-
-Could the same be achieved with a wrapper around `openssl` ? yes.
