Generate SSH key pairs (RSA, Ed25519) for secure server access. All keys are generated in your browser using the Web Crypto API — nothing is sent to any server.
The SSH Key Generator by TooliFyra is a free online tool that generates SSH key pairs for secure server authentication. Instead of using passwords, SSH keys provide cryptographic proof of identity for logging into servers, Git platforms, and remote machines.
The tool supports Ed25519 (modern, recommended), RSA 2048-bit, and RSA 4096-bit key types. All key generation happens in your browser using the Web Crypto API — your private key never leaves your device.
~/.ssh/authorized_keys file.SSH keys are far more secure than password authentication. They eliminate brute-force attacks, don't transmit passwords over the network, and work seamlessly with automated scripts and CI/CD pipelines. The free SSH key generator makes it easy to create properly formatted keys without installing command-line tools.
Server Administrators: Generate SSH keys for secure remote server access without password login.
Developers: Create key pairs for Git platform authentication (GitHub, GitLab, Bitbucket).
DevOps Engineers: Generate keys for automated deployment scripts and CI/CD pipelines.
Security-Conscious Users: Replace weak password authentication with cryptographic key-based authentication.
TooliFyra provides a fast, secure, and free SSH key generator that runs entirely in your browser. Your private key is never transmitted over the network, ensuring maximum security. The tool supports all major key types and provides properly formatted output ready for immediate use.
Yes, completely free with no usage limits, sign-up, or premium features.
Yes. All key generation happens in your browser using the Web Crypto API. Your private key is never sent to any server.
Ed25519 is recommended for most users — it's faster and more secure than RSA. Use RSA only if you need compatibility with older systems that don't support Ed25519.
Place the private key file on your local machine (e.g., ~/.ssh/id_ed25519), set correct permissions (chmod 600), then connect with: ssh -i ~/.ssh/id_ed25519 user@server
Yes. Copy the public key and paste it into GitHub Settings → SSH and GPG Keys → New SSH Key.
