| IvParameterSpec(byte[] iv)Creates an IvParameterSpec object using the bytes in  ivas the IV. | 
| IvParameterSpec(byte[] iv,
               int offset,
               int len)Creates an IvParameterSpec object using the first  lenbytes iniv, beginning atoffsetinclusive, as the IV. | 
public IvParameterSpec(byte[] iv)
iv as the IV.iv - the buffer with the IV. The contents of the buffer are copied to protect against subsequent
            modification.NullPointerException - if iv is nullpublic IvParameterSpec(byte[] iv,
                       int offset,
                       int len)
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.
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.IllegalArgumentException - if iv is null or (iv.length - offset < len)ArrayIndexOutOfBoundsException - is thrown if offset or len index bytes outside the iv.
