It's something like a CRC checksum, it checks the filesum to determine if the file is corrupted. When there is a mismatch, chances are your file is corrupted and you need to dl again. Especially useful for large files or multi-zip archives

is it worth downloading?

Yes because you can see if the files corrupt or been tampered with

I didnt see anything related to xda on google

I did, which is where the link came from using "what is md5 checksum" as the search term.

A lot of dodgy sites? XD could be a hacker gaining your trust and then he might get you to download a MD5 verification software that really gives him access to your machine?...

you need the original MD5 from when it was created. alot of devs give MD5's of files with the download link.

[Q] bad zip

This is probably a simple solution. I download a Rom or a file and when I check it it says bad zip. What am I doing wrong?

Probably ROM Manager. It'll give that some times. Just fix permissions in advanced settings.

Website xda
some of the file share sites won't download directly to the phone....try downloading to a PC then transfer file to phone...
Also, if you don't have it already, you should get the app 'Download All Files' for the phone. May not apply in this case but a must have app anyway.

I'm not sure what you meant but DL all files is a market app.
And I'm pretty sure it works with the XDA app.

CM10 Bootloops!!!

Last evening I attempted to flask Binary Bishop's JB 4.1.1. 7/30 build. Nuts! I followed the flashing instructions exactly and I am bootlooping at the CM9 screen. Are there any other steps/alternate methods to try to push this through? I'm assuming the answer is "bad download", but, I don't understand what that means exactly when I d/l'ed from the OP? Using CW non-touch recovery. 3 questions: is there any distinct advantage as far as integrity of the build by using the Goo app on the phone versus from the XDA website and then putting it on the phone, and, if I were to use the "Settings/Factory data reset" versus the one in CWM Recovery, what does it do differently? When it says at the bottom "erases all data on phone", how is that different than what factory reset in CWM does, as a practical matter? Is the TWRP recovery any more reliable for what I am trying to do? This just makes no sense that it bootloops when I am doing everything exactly as the OP says to!!!

Technically no. Are you checking the md5sum of the files you download? If the answer is no, you should be. If you use the Goo.im app it will automatically check them for you when it finishes downloading. Just because you are downloading from the recommended source does not mean that the file cant be corrupted during the download. Goo.im checks the md5sum for you when you go through the app.

Yes, thank you, I am using the GOO app on the phone to download the ROM. The MD5 is good. I am just beyond baffled as to why I cannot get thid damned thing to boot up. Would you be able to share exactly what steps you did to get yours going. All things being equal, it just makes no sense. I odin'ed back to stock, redid everything exactly as the OP says and it just will not boot, no matter what I do or wipe. PS: I'm using TWRP 2.2 recovery now. Doesn't seem to matter what I do.
Edit: Just switched back to CWM, followed the OP instructions to a "t", no go!!!
Edit: Just tried both the "Unofficial" and "Experimental" CM10 builds, still no go. WTF!!!??? Why can I get AOKP to boot alll the time? I "get" that it is JB, but the damn thing should either boot all the time or never boot, correct? (I'm sure it's not quite that simple.)

only 3% goes further than stops with some message as :MAJOR err CLASS,ERR_STATIC,SIN_HEAD_VER,ERR_DYNAMIC=failed to verify sin header.....something like that!

Bad post (had to delete it). Sory !
Puuush...
I haven't had an in depth look, but I'm guessing you could just extract the ftf and .sin then push them to the phone unsure if other steps are needed.

will be great to have,or if you have a solution!
If your ftf files are valid you should check your language&regional settings it should be U.K or something if you are coming from another regional settings.
After that you can flah via flashtool.

Thanx but...
i changed that but no go.If you mean it to change on PC!?
it goes only 3% and stops

Sorry been busy don't have time to do it, but try extracting the .ftf then use flashtool to to extract the .sin and finally mount the yaffs2 files and just push them to the phone. Then in cwm make sure you run fix permissions.

Heres the md5 sum I got. 84d1b95ad2347ec2a0879ba90d87982d
I'll try it here in a minute.
edit I got a status 6 error in TWRP
Its Because I Changed how the mount points were written so that If a variant tries to flash he wont get bricked.
So is there a work-around? Or wait for the fix?

I got it to work.
I kept getting status 6 error but it checked the "zip file signature verification" box for some reason. So I unchecked it and it worked ?
Don't know if you downloaded the ROM from dropbox or this new site Engine.
Didn't work at all from dropbox whether i checked or unchecked the "zip file signature verification" box but it worked at the new site.
