Constructor Detail

EcDH1KeyDerivationParams

public EcDH1KeyDerivationParams(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 Object 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 DHKeyDerivationParams

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 DHKeyDerivationParams

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 DHKeyDerivationParams

Returns:

The hash code of this object.
