SSH Key Generation FAQ
Everything you need to know about our process, pricing, and technical capabilities.
See Full FAQDifferent SSH key types offer different benefits: Ed25519: Modern, secure, and recommended for most users RSA (4096 bit): Widely supported and secure when using sufficient bits ECDSA: Good balance of security and performance Ed25519 is recommended for new deployments unless you have specific compatibility requirements.
SSH keys offer several advantages over passwords: Stronger security and resistance to brute-force attacks Automated and scriptable authentication No need to remember or type passwords Better audit trail of access
Using a passphrase is recommended because: Protects your private key if your computer is compromised Adds an extra layer of security Minimal inconvenience with SSH agents However, for automated scripts you might need to use keys without passphrases.
To use your SSH keys: Save the private key to ~/.ssh/id_rsa (or similar) Add the public key to ~/.ssh/authorized_keys on remote servers Set proper permissions (chmod 600 for private key) Optionally add to your SSH agent with ssh-add
Our key generation is secure because: Uses browser's native crypto API All generation happens client-side Follows cryptographic best practices No keys are transmitted or stored
