Constructor Detail

RC5Parameters

public RC5Parameters(long wordSize,
                     long rounds)

Create a new RC5Parameters object with the given word size and given rounds.

Parameters:

wordSize - The wordsize of RC5 cipher in bytes.

rounds - The number of rounds of RC5 encipherment.

Method Detail

clone

public java.lang.Object clone()

Create a (deep) clone of this object.

Overrides:

clone in class java.lang.Object

Returns:

A clone of this object.

getWordSize

public long getWordSize()

Get the wordsize of RC5 cipher in bytes.

Returns:

The wordsize of RC5 cipher in bytes.

getRounds

public long getRounds()

Get number of rounds of RC5 encipherment.

Returns:

The number of rounds of RC5 encipherment.

getPKCS11ParamsObject

public java.lang.Object getPKCS11ParamsObject()

Get this parameters object as an object of the CK_RC5_PARAMS class.

Specified by:

getPKCS11ParamsObject in interface Parameters

Returns:

This object as a CK_RC5_PARAMS object.

setWordSize

public void setWordSize(long wordSize)

Set the wordsize of RC5 cipher in bytes.

Parameters:

wordSize - The wordsize of RC5 cipher in bytes.

setMacLength

public void setMacLength(long rounds)

Set the number of rounds of RC5 encipherment.

Parameters:

rounds - The number of rounds of RC5 encipherment.

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 java.lang.Object

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 java.lang.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 java.lang.Object

Returns:

The hash code of this object.
