Change md5 on video files?

[Ruriko]

Is there a way to change MD5 hash on video files without raring?

This tutorial is only on PCs.

You will be needing a software for checking/creating file hash. If you don't have one, you can use QuickSFV.

Let's start changing MD5s. Say we have the files below that need MD5 change:

[FONT=Courier New]FILENAME        SIZE        MD5 hash
bolt.part1.rar         1,500,000     499934d3cc1c544c37f6f5d985a13685
bolt.part2.rar         1,500,000     a572b15572a7715df83e093ee2fb2bf9
bolt.part3.rar         1,500,000    c1291527060c81b590356195cdd18367
[/FONT][FONT=Courier New]bolt.part4.rar           416,344     a7d6ddfedc3d273ab91d46c389d110d8[/FONT]

Open notepad and type one RANDOM character, say "a" in this example, then save the file as MD5.txt

Open another instance of notepad and type the line below:

[B][FONT=Courier New][B][COLOR=red]FOR %%1 in (*.rar) do COPY %%1+MD5.txt[/COLOR][/B][/FONT][/B]

Save the file as ChangeMD5.BAT


RUN the batch file, ChangeMD5.BAT, by double clicking on it.

Filesize and filehash would be changed to:

[FONT=Courier New]FILENAME        SIZE        MD5 hash
bolt.part1.rar         1,500,00[B][COLOR=Red]2[/COLOR][/B]     [COLOR=red]815890400fa58d4010bf858fbe2d2c88[/COLOR]
bolt.part2.rar         1,500,00[B][COLOR=red]2[/COLOR][/B]     [COLOR=red]6b1dce05c261fe217d365077e9dd632c[/COLOR]
bolt.part3.rar         1,500,00[B][COLOR=red]2[/COLOR][/B]    [COLOR=red]250750017453d1fd70e77466b94d5dec[/COLOR]
bolt.part4.rar           416,34[B][COLOR=red]6[/COLOR][/B]     [COLOR=red]d6d90760657d4cc37d9b34fc44e19dc5[/COLOR][/FONT]

NOTE that the file sizes are now 2 bytes more than the original. MD5 hash changed as well.

Open WInRAR and test the archive. There must be NO ERRORS in the test operation. If tested OK, you can now upload the file to your preferred filehost.

I have been using this method for a long time to modify the MD5s of files that i upload. You can test whether this method can also be used on ZIP files. I would not recommend using this method on movie files because this will modify the original file. You don't want that. You should RAR the files so that you will just be modifying the CONTAINER and NOT THE CONTENT.
