Constructor Detail

RC2CbcParameters

public RC2CbcParameters(long effectiveBits,
                        byte[] initializationVector)

Create a new RC2CbcParameters object with the given effective bits and the initialization vector.

Parameters:

effectiveBits - The effective number of bits in the RC2 search space.

initializationVector - The initialization vector.

Preconditions:

(effectiveBits ≥ 1) and (effectiveBits ≤ 1024) and (initializationVector != null)

Method Detail

clone

public java.lang.Object clone()

Create a (deep) clone of this object.

Overrides:

clone in class RC2Parameters

Returns:

A clone of this object.

Postconditions:

(result != null) and (result instanceof RC2CbcParameters) and (result.equals(this))

getPKCS11ParamsObject

public java.lang.Object getPKCS11ParamsObject()

Get this parameters object as CK_RC2_CBC_PARAMS object.

Specified by:

getPKCS11ParamsObject in interface Parameters

Overrides:

getPKCS11ParamsObject in class RC2Parameters

Returns:

This object as CK_RC2_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 RC2Parameters

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 RC2Parameters

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 RC2Parameters

Returns:

The hash code of this object.
