Constructor Detail

RC5CbcParameters

public RC5CbcParameters(long wordSize,
                        long rounds,
                        byte[] initializationVector)

Create a new RC5CbcParameters object with the given word size, given rounds and the initialization vector.

Parameters:

wordSize - The wordsize of RC5 cipher in bytes.

rounds - The number of rounds of RC5 encipherment.

initializationVector - The initialization vector.

Preconditions:

(initializationVector != null)

Method Detail

clone

public java.lang.Object clone()

Create a (deep) clone of this object.

Overrides:

clone in class RC5Parameters

Returns:

A clone of this object.

Postconditions:

(result != null) and (result instanceof RC5CbcParameters) and (result.equals(this))

getPKCS11ParamsObject

public java.lang.Object getPKCS11ParamsObject()

Get this parameters object as an object of the CK_RC5_CBC_PARAMS class.

Specified by:

getPKCS11ParamsObject in interface Parameters

Overrides:

getPKCS11ParamsObject in class RC5Parameters

Returns:

This object as a CK_RC5_CBC_PARAMS object.

Postconditions:

(result != null)

getInitializationVector

public byte[] getInitializationVector()

Get the initialization vector.

Returns:

The initialization vector.

Postconditions:

(result != null)

setInitializationVector

public void setInitializationVector(byte[] initializationVector)

Set the initialization vector.

Parameters:

initializationVector - The initialization vector.

Preconditions:

(initializationVector != null)

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 RC5Parameters

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 RC5Parameters

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 RC5Parameters

Returns:

The hash code of this object.
