Is Ed25519 better than RSA?

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. ... It's also fast to perform batch signature verification with Ed25519.

How SSH public key looks like?

An SSH key is an alternate way to identify yourself that doesn't require you to enter you username and password every time. SSH keys come in pairs, a public key that gets shared with services like GitHub, and a private key that is stored only on your computer. If the keys match, you're granted access.
