  • IvParameterSpec

    public IvParameterSpec(byte[] iv)

    Creates an IvParameterSpec object using the bytes in iv as the IV.

    Parameters:

    iv - the buffer with the IV. The contents of the buffer are copied to protect against subsequent modification.

    Throws:

    NullPointerException - if iv is null

  • IvParameterSpec

    public IvParameterSpec(byte[] iv,
     int offset,
     int len)

    Creates an IvParameterSpec object using the first len bytes in iv, beginning at offset inclusive, as the IV.

    The bytes that constitute the IV are those between iv[offset] and iv[offset+len-1] inclusive.

    Parameters:

    iv - the buffer with the IV. The first len bytes of the buffer beginning at offset inclusive are copied to protect against subsequent modification.

    offset - the offset in iv where the IV starts.

    len - the number of IV bytes.

    Throws:

    IllegalArgumentException - if iv is null or (iv.length - offset < len)

    ArrayIndexOutOfBoundsException - is thrown if offset or len index bytes outside the iv.

  • getIV

    public byte[] getIV()

    Returns the initialization vector (IV).

    Returns:

    the initialization vector (IV). Returns a new array each time this method is called.
