Constructor Detail

EcDH1KeyDerivationParameters

public EcDH1KeyDerivationParameters(long keyDerivationFunction,
                                    byte[] sharedData,
                                    byte[] publicData)
Create a new EcDH1KeyDerivationParameters object with the given attributes.
Parameters:
keyDerivationFunction - 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

clone

public java.lang.Object clone()
Create a (deep) clone of this object.
Overrides:
clone in class DHKeyDerivationParameters
Returns:
A clone of this object.

getPKCS11ParamsObject

public java.lang.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 java.lang.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(java.lang.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.
