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.
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 . |
