All Implemented Interfaces:

Cloneable, AlgorithmParameterSpec

public final class EdDHParameterSpec
extends EdParameterSpec

This parameter class is intended for use with X25519 and X448. It extends the ordinary EdParameterSpec with additional parameters for a key derivation function (KDF). If no KDF parameters are present, then the raw secret will be generated.

Constructor Detail

EdDHParameterSpec

public EdDHParameterSpec(EdParameterSpec edParams,
                         KDFParameterSpec kdfParams)

Creates a new parameter spec object.

Parameters:

edParams - the elliptic curve domain parameters

kdfParams - the KDF parameters

EdDHParameterSpec

public EdDHParameterSpec(EdParameterSpec edParams)

Creates a new parameter spec object without KDF parameters. Hence, using this parameter instance the ECDH routine will output the raw secret.

Parameters:

edParams - the elliptic curve domain parameters

Method Detail

equals

public boolean equals(Object obj)

Overrides:

equals in class EdParameterSpec

hashCode

public int hashCode()

Overrides:

hashCode in class EdParameterSpec
