Security+ ยท 3.0 Security Architecture
Asymmetric encryption
Encryption where a public key encrypts and a private key decrypts (or the reverse for signatures). Slower than symmetric but solves key-distribution. Examples: RSA, ECDSA, Ed25519.
How this shows up at NCAE
SSH key-based auth (`authorized_keys`) is asymmetric. The scoring engine has the private key, your server has the public key. Your server NEVER sees the private key.
