SSH 密钥生成器
生成用于安全服务器认证的 SSH 密钥对。密钥在您的浏览器中本地生成。
Browser-generated keys
These keys are generated in your browser using Web Crypto API. For production use, consider using ssh-keygen on your local machine.
SSH Key Usage
- • Ed25519 is newer, faster, and recommended for most use cases
- • RSA 4096 is widely compatible but slower to generate
- • Save private key to ~/.ssh/id_ed25519 (chmod 600)
- • Add public key to server's ~/.ssh/authorized_keys
# Generate locally with ssh-keygen
ssh-keygen -t ed25519 -C "your@email.com"
ssh-keygen -t ed25519 -C "your@email.com"
SSH Keys - 技术详情
SSH keys provide secure, passwordless authentication to servers. Ed25519 is the modern, recommended algorithm. RSA 4096 offers broad compatibility. Never share your private key—only distribute the public key.
命令行替代方案
# Generate Ed25519 key (recommended)\nssh-keygen -t ed25519 -C 'your@email.com'\n\n# Generate RSA key\nssh-keygen -t rsa -b 4096 -C 'your@email.com'\n\n# Copy public key to server\nssh-copy-id user@server
