Struct CryptoHelper.SessionKeys

Namespace

FishMMO.Auth.Implementation

Assembly

FishMMO-AuthShared.dll

Container for derived session keys and prefixes.

public readonly struct CryptoHelper.SessionKeys : IDisposable

Implements

IDisposable

Inherited Members

ValueType.Equals(object)

ValueType.GetHashCode()

ValueType.ToString()

object.Equals(object, object)

object.GetType()

object.ReferenceEquals(object, object)

Remarks

Mutability: The byte[] fields are mutable references. Callers must not share or alias them, and must zeroize via ZeroMemory(byte[]) when no longer needed.

IDisposable usage: Implement using var keys = DeriveSessionKeys(…); to ensure Dispose() zeroes all key material when the scope exits. Because this is a readonly struct, the compiler calls Dispose() directly on the variable without boxing.

Constructors

SessionKeys(byte[], byte[], byte[], byte[])

public SessionKeys(byte[] clientToServerKey, byte[] serverToClientKey, byte[] clientPrefix, byte[] serverPrefix)

Parameters

clientToServerKey byte[]

serverToClientKey byte[]

clientPrefix byte[]

ServerToClientKey

public readonly byte[] ServerToClientKey

Field Value

byte[]

Methods

Dispose()

Zeroes all key material. Equivalent to ZeroAll(). Enables using var keys = …; for deterministic cleanup.

public void Dispose()

ZeroAll()

Zeroes all key material referenced by this instance.

public void ZeroAll()

Remarks

Ownership: SessionKeys is a transient container whose fields are typically copied into long-lived connection state after derivation. Calling ZeroAll() only zeroes the arrays referenced by THIS struct — it does not affect copies held by ConnectionEncryptionData or other consumers. Callers must manage key lifetime at the connection level.
