Method Detail

getUsagesRemaining

public long getUsagesRemaining()

getEncoded

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

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.

getNextKey

public XMSSPrivateKeyParameters getNextKey()

extractKeyShard

public XMSSPrivateKeyParameters extractKeyShard(int usageCount)

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.

toByteArray

@Deprecated
public byte[] toByteArray()

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

Description copied from interface: XMSSStoreableObjectInterface

Specified by:

toByteArray in interface XMSSStoreableObjectInterface

Returns:

Byte representation of object.

getIndex
