Field Detail

blockSize_

protected int blockSize_
This is the block size in byte of the underlying cipher, e.g. 8 for DES and Triple DES and 16 for AES.

iv_

protected byte[] iv_
The initialization vector for CBC mode of the cipher.

data_

protected byte[] data_
The data to be used in the key derivation. It must have a length that is a multiple of the block-size of the underlying cipher.
Constructor Detail

CbcEncryptDataParameters

protected CbcEncryptDataParameters(int blockSize,
                                   byte[] iv,
                                   byte[] data)
Create a new CbcEncryptDataParameters object with the given IV and data.
Parameters:
blockSize - The block size of the cipher.
iv - The initialization vector which's length must be block size.
data - The key derivation data which's length must be multiple of the block size.
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.

getBlockSize

public int getBlockSize()
Get the block size of the underlying cipher in bytes.
Returns:
The block size in bytes.

getInitializationVector

public byte[] getInitializationVector()
Get the initialization vector for CBC mode.
Returns:
The initialization vector.

setInitializationVector

public void setInitializationVector(byte[] iv)
Set the initialization vector for CBC mode.
Parameters:
iv - The initialization vector.

getData

public byte[] getData()
Get the data for key derivation.
Returns:
The data.

setData

public void setData(byte[] data)
Set the key derivation data.
Parameters:
data - The key derivation data.

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.
