PivEccPublicKey Constructor

PivEccPublicKey(ReadOnlySpan<Byte>)

Create a new instance of an ECC public key object based on the given point.

C#

public PivEccPublicKey(ReadOnlySpan<byte> publicPoint)

Parameters

Type	Name	Description
System.ReadOnlySpan<System.Byte>	publicPoint	The public point to use to build the object.

Exceptions

Type	Condition
System.ArgumentException	The format of the public point is not supported.

Remarks

The point must be provided in the following form

  04 || x-coordinate || y-coordinate
  each coordinate must be the same size, either 32 bytes (256 bits)
  or 48 bytes (384 bits).
  Prepend 00 bytes if necessary.

The class will determine the algorithm (PivAlgorithm.EccP256 or PivAlgorithm.EccP384) based on the size of the point.
