It started as a pet project and I wanted to create a native app by writing it in Java.\nDuring my work I discovered that extracting certificates in other tools can sometimes be troublesome, so I used that as a use-case to create an app in Java, compile that to native OS app so others don't need Java to run it.\nIt made my work easier for maintaining trust-stores and I hope it made others life also easier.\n\nI have created this tool with ❤️ and passion, mostly during evening and night hours. If you use my tool and want to appreciate the work I have done, please consider to sponsor this project as a way to contribute back to the community.\nThere are 3 options available to pick from: [GitHub](https://github.com/sponsors/Hakky54), [Ko-fi](https://ko-fi.com/hakky54) and [Open Collective](https://opencollective.com/hakky54)\n\n## Demo\n![alt text](https://github.com/Hakky54/certificate-ripper/blob/master/images/demo.gif?raw=true)\n\n## Advantages\n- It is fast\n- Easy to use\n- No openssl required\n- Runs on any Operating System\n- Can be used with or without Java, native executables are present in the releases\n- Extracts all the sub-fields of the certificate\n- Certificates can be formatted to PEM format\n- Bulk extraction of multiple different urls with a single command is possible\n- Extracted certificates can be stored automatically into a p12 truststore\n- Works also behind a proxy\n- Supported protocols: \n  - https (Hypertext Transfer Protocol Secure)\n  - wss (WebSocket Secure)\n  - ftps (File Transfer Protocol Secure)\n  - smtps (Simple Mail Transfer Protocol Secure)\n  - imaps (Internet Message Access Protocol Secure)\n  - Database:\n    - PostgreSQL\n    - MySQL\n\n## Installing\n\nThe executables are available for download in the [Releases](https://github.com/Hakky54/certificate-ripper/releases).
