Hi All,
I'm trying to encrypt the message in the gif image.
is there any algorithm for that to do?
I'm able to get create new image ,and even i retrieved the byte[] of the image.
I want to know how to add the "message" in that byte[].
As we know that messages needed to added at LSB inorder to retaining the
original image.I dont know how to add at LSB.

When i was surfing thro google i came across the contents at http://www.dreamincode.net/forums/showtopic27950.htm
In that i couldnt get "Bit_Conversion" and "Encode_text" part..
can anyone pl help me ASAP..
Thanks in Advance

-Thanks & Regards,
Hamsa

To learn how to do bitwise operations in Java, try a tutorial such as this one.

You will find the Integer method toBinaryString() to be helpful in visualizing what is happening.
