Constructor Detail

DESOperationModeInitializationVectorSpec

public DESOperationModeInitializationVectorSpec(byte[] iv)
                                         throws IllegalBlockSizeException

Creates a new DESOperationModeInitializationVectorSpec.

Parameters:

iv - the initialization vector to set.

Throws:

IllegalBlockSizeException - if length of iv shorter than 8 bytes. If it is longer, we use only the first 8 bytes from iv.

DESOperationModeInitializationVectorSpec

public DESOperationModeInitializationVectorSpec(byte[] iv,
                                                int offset)
                                         throws IllegalBlockSizeException

Creates a new DESOperationModeInitializationVectorSpec.

Parameters:

iv - the initialization vector to set.

offset - the offset in iv, where iv starts.

Throws:

IllegalBlockSizeException - if length of iv shorter than offset+8 bytes. If it is longer, we use only the first 8 bytes from iv, starting at offset.

DESOperationModeInitializationVectorSpec

public DESOperationModeInitializationVectorSpec(DESOperationModeInitializationVectorSpec iv)

Creates a new DESOperationModeInitializationVectorSpec from an existing one.

Parameters:

iv - the initialization vector to set.

Method Detail

clone

public Object clone()
             throws CloneNotSupportedException

Creates and returns a deep copy of this object.

Returns:

a clone of this instance.

Throws:

CloneNotSupportedException - if the object's class does not support the Cloneable interface. Subclasses that override the clone method can also throw this exception to indicate that an instance cannot be cloned.

Cloneable

equals

public boolean equals(Object obj)

Indicates whether some other object is "equal to" this one.

Parameters:

obj - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.

See Also:

hashCode(), Hashtable

hashCode

public int hashCode()

Returns a hash code value for the object.

Returns:

a hash code value for this object.

See Also:

equals(java.lang.Object), Hashtable

toString

public String toString()

Returns a string representation of the object.

Returns:

a string representation of the object.

getIv

public byte[] getIv()

Returns the initialization vector.

Returns:

a initialization vector as byte[8].
