### Generate Let's Encrypt certificate with goshs

Source: https://docs.goshs.de/usage/tls/lets-encrypt/index.html

Starts goshs with Let's Encrypt enabled, specifying the contact email and comma-separated domain names. Requires an A DNS record pointing to the server's IP and root privileges so Let's Encrypt can reach ports 80 and 443. On success, creates files named key and cert.

```bash
goshs -s -sl -sle your@mail.com -sld your.domain.com,your.seconddomain.com
```

--------------------------------

### Start goshs with hashed password

Source: https://docs.goshs.de/usage/authentication/basic/index.html

Starts goshs with basic authentication using a hashed password. The hash is generated with goshs -H. Enclose the argument in single quotes to prevent the $ signs in the hash from breaking the command.

```bash
goshs -b 'test:$2a$14$zQCKs8RTPVQEBKKvzDgrAur9DJ4MZ0hLYNjPymg3.RB8T8C/xIqpG'
