Interface SignatureValidator

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface SignatureValidator

General purpose functional interface to verify signatures.
Built in validators:

• PASS: will always report true
• FAIL: will always report false
• YGGDRASIL: Uses SHA1 with RSA and Yggdrasil Public Key for verifying signatures
• from(Player): Uses SHA256 with RSA and the Player's PlayerPublicKey.publicKey()
• from(PublicKey, KeyUtils.SignatureAlgorithm): General purpose factory method

static SignatureValidator	from(PublicKey publicKey, KeyUtils.SignatureAlgorithm algorithm)
static @Nullable SignatureValidator	from(Player player)	Creates a validator from the player's public key using SHA256 with RSA
boolean	validate(byte[] payload, byte[] signature)	Validate signature.
default boolean	validate(Consumer<NetworkBuffer> payload, byte[] signature)

Field Details

PASS

static final SignatureValidator PASS

FAIL

static final SignatureValidator FAIL

YGGDRASIL

static final SignatureValidator YGGDRASIL

Method Details

validate

boolean validate(byte[] payload,
 byte[] signature)

Validate signature. This should not throw any exception instead it should return false.

Returns:

true only if the signature is valid

validate

default boolean validate(Consumer<NetworkBuffer> payload,
 byte[] signature)

from

static SignatureValidator from(PublicKey publicKey,
 KeyUtils.SignatureAlgorithm algorithm)

from

@Nullable
static @Nullable SignatureValidator from(Player player)

Creates a validator from the player's public key using SHA256 with RSA

Parameters:

player - source of the key

Returns:

null if the player didn't send a public key
