Constructor Detail

EcDH1KeyDerivationParameters

public EcDH1KeyDerivationParameters(long kdf,
                                    byte[] sharedData,
                                    byte[] publicData)

Create a new EcDH1KeyDerivationParameters object with the given attributes.

Parameters:

kdf - The key derivation function used on the shared secret value. One of the values defined in KeyDerivationFunctionType.

sharedData - The data shared between the two parties.

publicData - The other partie's public key value.

Method Detail

getPKCS11ParamsObject

public sun.security.pkcs11.wrapper.CK_ECDH1_DERIVE_PARAMS getPKCS11ParamsObject()

Get this parameters object as an object of the CK_ECDH1_DERIVE_PARAMS class.

Returns:

This object as a CK_ECDH1_DERIVE_PARAMS object.

getSharedData

public byte[] getSharedData()

Get the data shared between the two parties.

Returns:

The data shared between the two parties.

setSharedData

public void setSharedData(byte[] sharedData)

Set the data shared between the two parties.

Parameters:

sharedData - The data shared between the two parties.

toString

public String toString()

Returns the string representation of this object. Do not parse data from this string, it is for debugging only.

Overrides:

toString in class DHKeyDerivationParameters

Returns:

A string representation of this object.

equals

public boolean equals(Object otherObject)

Compares all member variables of this object with the other object. Returns only true, if all are equal in both objects.

Overrides:

equals in class DHKeyDerivationParameters

Parameters:

otherObject - The other object to compare to.

Returns:

True, if other is an instance of this class and all member variables of both objects are equal. False, otherwise.

hashCode

public int hashCode()

The overriding of this method should ensure that the objects of this class work correctly in a hashtable.

Overrides:

hashCode in class DHKeyDerivationParameters

Returns:

The hash code of this object.
