Before I can report the error I have to make sure the checksum of my fasm.pdf is correct, if anyone can post their checksums of the file first (the latest one) Md5 or sha-1 please.

Also, why doesn't fasm include checksums in its own special thread on the forum or on the front page?

I wonder how often people who request checksums for downloaded files actually have their downloads corrupted. ZIP archives have CRC-32 checksums for every file, and FASM.pdf comes in one of ZIP-archived packages, so your file is not corrupted. It might only be from an older version but you said nothing about that.

There are more ways to get corrupted files other than Winzip's alerts. I still would prefer to have at least three other users provide the checksums. Also, crc32 is unreliable (Sure it is useable, but I prefer sha-1 please)

Appreciate this from 3 other users if you could visit https://www.online-convert.com/ and select sha-1 from the hash generator and test your fasm.pdf file there. It is also perfectly fine if you tested the fasm zip package, it would actually be better if you tested the whole archive for me.

I ask this because when I download the fasm package, I get a unique copy of it that is not present anywhere on the internet but on my computer. It has a unique signature that nobody else uses. It's "frustrating", it may be because nobody has registered the file anywhere yet, but I like to make sure.

Safety of operation comes first Smile

Do not be afraid to post the sha-1 signature, hashing algorithms are designed to not be reversible, so it would be extremely difficult to tell what is exactly in your files, so you can safely post the signatures. Knowing this, I'm sure that many people will provide signatures Smile

Author is also welcome to post signature of fasm.pdf, I'm sure that forum users will find it "collective" amusing Wink

I hope not the forum code itself is generous on that regard. We can not afford to live by a century old trick of having to rely on hashes.

You’re talking about just not being sure your version containing mistake is the actual version. If you see a mistake, just speak about it. There’s nothing about safety here, you’ve already opened the (probably malicious) document.

If you’re so lucky that having a CRC-32 collision you still get a valid and readable PDF file, it’s OK to receive a response that your version is broken. But believe me, it is not. OSI model has 7 levels in it, some of which also have checksums.

Cool story, bro. Let me guess, you’re one of those guys unreasonably thinking HTTPS is a must and making up a story of having your download intercepted? What makes you think your downloaded copy is different from the original?

Have you checked the last update performed by your web browser to also have valid checksum? How do you make sure the SHA1 value posted by anyone here has not been replaced by a malware injected through the bug in the latest update of your OS?

---

And finally… Do you really want to report a documentation bug or just want to look clever by writing commonly known things like these?

Hi, I see that you are back again, I appreciate your input that relates to convenience. I am not sure what is going on here, but thanks for your input again.

I am looking forward to have you back again. I am hoping that others will get a chance to respond as well.

Your mostly welcome.

The downloads are forced to be over TLS (aka HTTPS) so you will have an original file. Don't worry about it.

Thanks for more replies, would you mind posting the hash anyway?

There ARE situations that can still "corrupt" the files. Local computer problems (malware for example) and other issues like server side scripting Smile

I APPRECIATE hashes if anyone would provide them, thanks. Smile

SHA1 and especially MD5 are no longer deemed secure, so I provide SHA256 sums of various fasm files here:

Check your files as much as you want!

However, I suggest that you only use local has sum calculators, not online one. For example you can download https://ftp.gnu.org/gnu/coreutils/?C=M;O=D
GNU coreutils package if it's not installed in your system yet, compile it from source and there is sha256sum.

Thanks. Can you confirm that what you see in this picture correlates with line 4 in your hash list (fasmw17304.zip)

(It looks ok to me)

The word error in the fasm.pdf file can be found by searching for "dot it", there is only one hit on that search phrase so it can be easily found.

Wow! So, you believe you may have malware that changes arbitrary data downloaded to your computer but still trust the hash you receive from an online service to be valid? And/or trust your offline hashing tool to be downloaded without interception? And trust your image has been uploaded without changes and nobody gives you back your original image instead of the malware-replaced image everyone else sees?

I really have nothing to say here then. Some people just like to have useless rituals, kind of cargo cult. But that’s OK, these cults are usually defeated by proper education. It’s just terrible when they make other people follow the same rituals.

This phrase can even be found in the online version of the manual, easily confirmed. Yes, there is a typo there.
