IvParameterSpec(byte[] iv)
Uses the bytes in iv as the IV. |
|
IvParameterSpec(byte[] iv,
int offset,
int len)

public IvParameterSpec(byte[] iv)
iv as the IV.
iv - the buffer with the IV
public 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 IVoffset - the offset in iv where the IV startslen - the number of IV bytes| Method Detail |
