Otherwise, the official page: [OpenSSL.Wiki: Binaries](https://wiki.openssl.org/index.php/Binaries) contains useful URLs for downloading and installation guides. 24 | 25 | ```bash 26 | openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout localhost.key -out localhost.crt -passin pass:YourSecurePassword 27 | ``` 28 | 29 | This command will generate two files: `localhost.crt` and `localhost.key`. 30 | 31 | ## License 32 | 33 | Feel free to use the code in this repository as it is under MIT license. 34 | 35 | Buy Me a Coffee at ko-fi.com 36 |
