Какой тип SSH-ключей рекомендуется использовать для обеспечения безопасности соединений?

To ensure the security of SSH connections, it is recommended to use Ed25519 or ECDSA keys. These key types have the following advantages:

• Higher cryptographic resilience with smaller key sizes.
• Fast generation and verification of keys.
• Supported by modern SSH clients and servers.

For example, to generate an Ed25519 key, you can use the command:

ssh-keygen -t ed25519 -C "your_email@example.com"

RSA keys are also widely used, but it is recommended to choose a key length of at least 2048 bits, preferably 4096 bits for enhanced security.
