About OpenSSL
OpenSSL is a robust, full-featured open-source toolkit implementing the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols, as well as a general-purpose cryptography library.
This tool helps you construct OpenSSL commands without memorizing the syntax. It covers the most common operations for certificate management, key generation, encryption, and format conversion.
Frequently Asked Questions
Do I need OpenSSL installed?
Yes. This tool generates OpenSSL commands for you to run on your own machine. You need OpenSSL installed to execute them. Most Linux/macOS systems have it pre-installed. Windows users can use WSL or download OpenSSL.
What does each output parameter mean?
- -out specifies the output file path. -keyout specifies where to save the private key. -newkey generates a new key. -nodes means "no DES" (no passphrase on the private key). -subj provides certificate subject details inline.
Is this tool secure?
This tool runs entirely in your browser. No data is sent to any server. The generated commands are for you to run locally on your own machine.
