Method Detail

getEncoded

public byte[] getEncoded()
                  throws java.io.IOException

Deprecated.

Description copied from interface: Encodable

Return a byte array representing the implementing object.

Specified by:

getEncoded in interface Encodable

Returns:

a byte array representing the encoding.

Throws:

java.io.IOException - if an issue arises generation the encoding.

toByteArray

@Deprecated
public byte[] toByteArray()

Deprecated. use getEncoded() - this method will become private.

Description copied from interface: XMSSStoreableObjectInterface

Create byte representation of object.

Specified by:

toByteArray in interface XMSSStoreableObjectInterface

Returns:

Byte representation of object.

getIndex

public long getIndex()

Deprecated.

getUsagesRemaining

public long getUsagesRemaining()

Deprecated.

getSecretKeySeed

public byte[] getSecretKeySeed()

Deprecated.

getSecretKeyPRF

public byte[] getSecretKeyPRF()

Deprecated.

getPublicSeed

public byte[] getPublicSeed()

Deprecated.

getRoot

public byte[] getRoot()

Deprecated.

getParameters

public XMSSMTParameters getParameters()

Deprecated.

getNextKey

public XMSSMTPrivateKeyParameters getNextKey()

Deprecated.

extractKeyShard

public XMSSMTPrivateKeyParameters extractKeyShard(int usageCount)

Deprecated.

Return a key that can be used usageCount times.

Note: this will use the range [index...index + usageCount) for the current key.

Parameters:

usageCount - the number of usages the key should have.

Returns:

a key based on the current key that can be used usageCount times.

destroy

public void destroy()

Deprecated.

Destroy this key, zeroizing the secret key material it holds: the seed the WOTS+ secret keys are derived from, the PRF key that randomizes message digests, and the WOTS+ secret keys the per-layer BDS traversal states retain for the leaves they last processed.

The public seed, the root, the index and the traversal states' tree nodes are retained - none of them is secret. After destruction isDestroyed() returns true and getSecretKeySeed(), getSecretKeyPRF(), getEncoded(), getNextKey() and extractKeyShard(int) throw IllegalStateException; a signature attempt fails before the index is advanced. Keys previously split off this one hold their own copies of the seeds and are unaffected.

Specified by:

destroy in interface javax.security.auth.Destroyable

isDestroyed

public boolean isDestroyed()

Deprecated.

Specified by:

isDestroyed in interface javax.security.auth.Destroyable
