image - Retrive combined files using java? -

Please consider this question. Now I know how to use Java files separately in those composite files?

1. Open the composite file as binary in Java
2. Bytes Sequence 0x52 0x61 0x72 0x21 0x1A 0x07 0x00
3. If you get only one event, then this is the beginning of the RAR file (as it starts with 0x52 byte.
4. If you Find multiple events, you may have to use the JPEG header to guess which real RAR starts.

   I get the JPEG header from You may not be able to use it, but you may be able to use it to start the correct RAR header or segment. Alternatively, you can modify your hidden scheme so that it is easy for the right recipient to start right rar One possible way is to add the number of bytes by using the image in 4, and add at the end of JPEG. Then add the RAR. If you have multiple matching tar byte sequence (0x52 0x61 ...), then the correct one is that which is before 4 byte encoding of the number bytes of that point (-4 at all.)
