Constructor Detail

DHKeyDerivationParams

protected DHKeyDerivationParams(long kdf,
                                byte[] publicData)

Create a new DHKeyDerivationParameters object with the given attributes.

Parameters:

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

publicData - The other partie's public key value.

Method Detail

getKeyDerivationFunction

public long getKeyDerivationFunction()

Get the key derivation function used on the shared secret value.

Returns:

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

getPublicData

public byte[] getPublicData()

Get the other partie's public key value.

Returns:

The other partie's public key value.

setKeyDerivationFunction

public void setKeyDerivationFunction(long kdf)

Set the key derivation function used on the shared secret value.

Parameters:

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

setPublicData

public void setPublicData(byte[] publicData)

Set the other partie's public key value.

Parameters:

publicData - The other partie's public key value.

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 Object

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 Object

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 Object

Returns:

The hash code of this object.
