Detailed Description

Wrapper class to pair a XMSS_WOTS_PublicKey with an XMSS Address. Since the PK_Ops::Verification interface does not allow an extra address parameter to be passed to the sign(RandomNumberGenerator&), the address needs to be stored together with the key and passed to the XMSS_WOTS_Verification_Operation() on creation.

Return the estimated strength of the underlying key against the best currently known attack. Note that this ignores anything but pure attacks against the key itself and do not take into account padding schemes, usage mistakes, etc which might reduce the strength. However it does suffice to provide an upper bound.

Returns
estimated strength in bits
