Method Detail

getIndex

long getIndex()

Return the index of the next signature.

Returns:

the index number for the next signature.

getUsagesRemaining

long getUsagesRemaining()

Return the number of usages left for the private key.

Returns:

the number of times the key can be used before it is exhausted.
