Field Details

offset

protected ECPoint offset

lookupTable

protected ECLookupTable lookupTable

Lookup table for the precomputed ECPoints used for a fixed point multiplication.

width

protected int width

The width used for the precomputation. If a larger width precomputation is already available this may be larger than was requested, so calling code should refer to the actual width.
