Struct ServerKeyPair 

pub struct ServerKeyPair { /* private fields */ }

An RSA key pair for the Minecraft login handshake.

Generated once at server startup. The public key is sent to clients in ClientboundHelloPacket; the private key decrypts the client’s shared secret.

Implementations

impl ServerKeyPair

pub fn generate() -> Result<Self, CryptoError>

Generates a new 1024-bit RSA key pair.

Errors

Returns CryptoError::KeyGeneration if the OS RNG or RSA generation fails.

pub fn public_key_der(&self) -> &[u8]

Returns the DER-encoded public key (X.509 SubjectPublicKeyInfo).

pub fn public_key(&self) -> &RsaPublicKey

Returns a reference to the RSA public key.

pub fn decrypt(&self, ciphertext: &[u8]) -> Result<Vec<u8>, CryptoError>

Decrypts data encrypted with the public key (PKCS#1 v1.5 padding).

Used to decrypt both the shared secret and the verification challenge.

Errors

Returns CryptoError::Decryption if decryption fails.

pub fn decrypt_shared_secret( &self, encrypted_secret: &[u8], ) -> Result<[u8; 16], CryptoError>

Decrypts the client’s shared secret and validates its length.

The shared secret must be exactly 16 bytes (128-bit AES key).

Errors

Returns CryptoError if decryption fails or the decrypted secret is not 16 bytes.

impl Debug for ServerKeyPair

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
