Today, the RSA is the most widely used public-key algorithm for SSH key. But compared to Ed25519, it’s slower and even considered not safe if it’s generated with the key smaller than 2048-bit length. The Ed25519 public-key is compact. … Generating the key is also almost as fast as the signing process.
