Method Detail

detach

protected ECPoint detach()

Specified by:

detach in class ECPoint

getYCoord

public ECFieldElement getYCoord()

Description copied from class: ECPoint

Returns the y-coordinate. Caution: depending on the curve's coordinate system, this may not be the same value as in an affine coordinate system; use normalize() to get a point where the coordinates have their affine values, or use getAffineYCoord() if you expect the point to already have been normalized.

Overrides:

getYCoord in class ECPoint

Returns:

the y-coordinate of this point

getCompressionYTilde

protected boolean getCompressionYTilde()

Specified by:

getCompressionYTilde in class ECPoint

add

public ECPoint add(ECPoint b)

Specified by:

add in class ECPoint

twice

public ECPoint twice()

Specified by:

twice in class ECPoint

twicePlus

public ECPoint twicePlus(ECPoint b)

Overrides:

twicePlus in class ECPoint

negate

public ECPoint negate()

Specified by:

negate in class ECPoint
