Class XWingPrivateKeySpec

java.lang.Object

zeroecho.core.alg.xwing.XWingPrivateKeySpec

All Implemented Interfaces:

Destroyable, AlgorithmKeySpec

public final class XWingPrivateKeySpec
extends Object
implements AlgorithmKeySpec, Destroyable

Encoded representation of an X-Wing private key as its 32-byte seed.

X-Wing uses a raw seed encoding for private keys (no DER/PKCS#8), as BouncyCastle 1.86 has no JCA/JCE provider binding for X-Wing. The seed allows deterministic reconstruction of the full X-Wing private key via XWingPrivateKeyParameters.

This class implements Destroyable to allow zeroing of key material when the spec is no longer needed.

Since:

1.0

Constructor Details

XWingPrivateKeySpec

public XWingPrivateKeySpec(byte[] seed)

Constructs a new spec from a raw X-Wing private key seed.

Parameters:

seed - 32-byte private key seed

Throws:

NullPointerException - if seed is null

IllegalArgumentException - if the seed is not exactly 32 bytes

Method Details

rawSeed

public byte[] rawSeed()

Returns a defensive copy of the raw seed bytes.

Returns:

seed bytes

Throws:

IllegalStateException - if this spec has been destroyed

marshal

public static PairSeq marshal(XWingPrivateKeySpec spec)

Serializes this spec to a PairSeq.

Parameters:

spec - the spec to serialize

Returns:

serialized representation

unmarshal

public static XWingPrivateKeySpec unmarshal(PairSeq p)

Deserializes a spec from a PairSeq.

Parameters:

p - serialized representation

Returns:

reconstructed spec

Throws:

IllegalArgumentException - if required field is missing
