Great thank you!
for the record
DSA even no longer supported since OpenSSH version 7
The Ed25519 was introduced on OpenSSH version 6.5. It’s the EdDSA implementation using the Twisted Edwards curve. It’s using elliptic curve cryptography that offers a better security with faster performance compared to DSA or ECDSA.
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 only contains 68 characters, compared to RSA 3072 that has 544 characters. Generating the key is also almost as fast as the signing process. It’s also fast to perform batch signature verification with Ed25519. It’s built to be collision resilence. Hash-function collision won’t break the system.
