Org.BouncyCastle.Crypto.Parameters.X448PublicKeyParameters

public sealed class X448PublicKeyParameters : AsymmetricKeyParameter
X448 public key (RFC 7748). Holds the 56-byte u-coordinate of the peer's curve point. The encoding is stored verbatim; validation of the point is performed during scalar multiplication in the agreement primitive.
public static readonly int KeySize

Length in bytes of an X448 public key encoding (56).

public X448PublicKeyParameters(byte[] buf)

Construct from a 56-byte buffer holding the encoded u-coordinate.

public X448PublicKeyParameters(byte[] buf, int off)

Construct from buf at off; reads KeySize bytes.

public X448PublicKeyParameters(Stream input)

Read the 56-byte encoded u-coordinate from input.

public void Encode(byte[] buf, int off)

Write the 56-byte encoded u-coordinate into buf at off.

public byte[] GetEncoded()

Return a fresh copy of the 56-byte encoded u-coordinate.
