Constructor Detail

RC5MacGeneralParameters

public RC5MacGeneralParameters(long wordSize,
                               long rounds,
                               long macLength)

Create a new RC5MacGeneralParameters object with the given word size, given rounds and the MAC length.

Parameters:

wordSize - The wordsize of RC5 cipher in bytes.

rounds - The number of rounds of RC5 encipherment.

macLength - The requested length of the MAC.

Method Detail

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)

getMacLength

public long getMacLength()

Get the length of the MAC produced, in bytes.

Returns:

The length of the MAC produced, in bytes.

setMacLength

public void setMacLength(long macLength)

Set the length of the MAC produced, in bytes.

Overrides:

setMacLength in class RC5Parameters

Parameters:

macLength - The length of the MAC produced, in bytes.

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.
