Comparing SSH encryption algorithms: RSA, DSA, ECDSA, or EdDSA?
This article compares the widely adopted asymmetric crypto algorithms. In the PKI world they are RSA, DSA, ECDSA, and EdDSA. Which SSH crypto algorithm is the best?
"When it comes down to it, the choice is between RSA 2048⁄4096 and Ed25519 and the trade-off is between performance and compatibility. RSA is universally supported among SSH clients while EdDSA performs much faster and provides the same level of security with significantly "
