~~The easiest way to create self-signed certificates. Ever.~~
Handy simple tool for common certificate-related operations.
```bash $ certainly test.example.com test2.example.com foo.local 10.0.200.36 Writing test.example.com.key Writing test.example.com.crt
$ certainly --inspect test.example.com.crt Self-signed certificate Created on: 2018-09-06 01:30:45 UTC Expires on: 2028-09-03 01:30:45 UTC Domains: DNS: test.example.com DNS: test2.example.com DNS: foo.local IP: 10.0.200.36
$ certainly --inspect twitter.com Certificate signed by DigiCert SHA2 High Assurance Server CA Created on: 2018-07-17 00:00:00 UTC Expires on: 2019-08-22 12:00:00 UTC Domains: DNS: twitter.com DNS: www.twitter.com ```

--std will output both key and certificate to STDOUT instead of writing files.--double-std will output the key to STDERR and the certificate to STDOUT instead, so redirection can be used to write or pipe files where needed efficiently. Take care of checking the key is actually formatted properly and not an error message though!
--inspect outputs terse information about the passed certificate file (or url) and exits.
--make-ca creates a key/certificate pair suitable for issuing instead. Use with --ca.
--ca NAME signs a certificate with a CA pair instead of self-signing. Provide only the common filename, without the .crt and .key extensions.
--client creates client certificates rather than server ones.
--rsa creates 4096-bit RSA certificates instead of 256-bit ECDSA ones.See the man page for more.
