Crypt::ECDSA::Point 0.069

Crypt::ECDSA::Point is a Perl module that contains elliptic curve points for EC cryptography.

METHODS

new

Constructor. Takes the following named pair arguments:

X => x coordinate,
Y => y coordinate,
curve => Crypt::ECDSA::Curve derived curve,
order => point order,
is_infinity => set to 1 if this is to be the point at infinity (optional)

X

Returns or sets the point's x coordinate

Y

Returns or sets the point's y coordinate

order

returns or sets the point order, if known

order

Returns or sets the Crypt::ECDSA::Curve upon which the point exists

is_point_at_infinity

Returns 1 if the point is the point at infinity for the EC curve,
otherwise undef.

deep_copy

Overloaded to '='
Returns a new point that copies the internals of the point (a cloned copy
rather than just a reference).

add

my $P3 = $P1 + $P2;

Overloaded to '+'
Returns the point that is the sum of two points on the curve

double

my $double = $p->double();

returns a point that is the point's double on the curve.

multiply

my $Q = $G * $d;

Multiply a point by a scalar (not a point by a point!)

Overloaded to '*'
Note: in order to be sure the proper multiply is done, I suggest that a mutiply
of point $P by scalar $k be written $P * $k, not $k * $P.

is_equal_to

if( $p1 == $p2) { ; }

Overloaded to '=='
Returns 1 if the points are equal (on the same curve as well).
