I found this tutorial very useful you are the best!

[@FabioMusanni]

Thank you very much! I'm glad it helped. Stay tuned, a lot more to come 😉🧐

[@raquelibanezlopez8539]

Thank you so much, Fabio. This tutorial saved my life! Awesome!

[@FabioMusanni]

Hello Raquel, thank you so much for the comment! 😊 I'm so happy I saved a life 😁 Jokes aside, glad it helped 😉

Me haz salvado la vida!!! Michas gracias!!

[@patfacunla1687]

Thank You for this wonderful tutorial!

[@metalalive2006]

since there is no cryptographical hash algorithm which has exactly zero collision probability, what are possible strategies to handle collision for the application which requires the message digest (the hashed value of the file content) as an index to uniquely identify the file in your storage ?

[@bn_ln]

let each hash be the key to a list, and then search the list.

[@FabioMusanni]

Thanks for the comment and sorry for my late reply. If you use sha-256 there is a really really remote probability of collision and you would have to hash loads (4.8 x 10^38) of files to even have one (I'd say it's impossible to have a collision among the files in your hard drives). That being said, if you want to decrease this probability even more, you could use the size of the file too. It's already extremely difficult for a file to have the same hash as a completely different file, let alone the same size as well. Maybe add the size in bytes at the beginning of the hash string and use size+hash as the index. This is just an idea. 😊 🤓

Thanks. You saved me a few hours. Able to verify my incoming file's checksum, now. It was unknown hash type and unknown range of the data. Turns out my input's header and footer chunks were not included in their provided checksum.

I'm glad the video helped! I also created a version with the GUI if you want to check it out: kzbin.info/www/bejne/pqrVoaFtadyjj8U 😊💪

Can you find a two different word with the same hashes ? Is it possible ?

[@FabioMusanni]

Hello Miranda 😊 It's possible, however, the question should be: how long would it take to find one collision? The first SHA-1 collision was found/created on purpose in 2017 after 9 quintillions computations in total (you can find more info at: shattered dot io). A SHA-256 collision has never been found, so if you use it, I wouldn't worry about finding a collision 🤓

[@EmmzNFT]

@@FabioMusanni really ? i can't manage to find the Collision or the said 2 words with same hash

[@FabioMusanni]

Exactly, if they haven't found one even trying with A LOT of computational power, it would be a sort of miracle if that happened to you by chance 😊

[@jnicholas846]

Thank you very much sir!

[@akhils4673]

sir how to reverse sha256

[@adithyavedula1270]

It would take you billions of years, that's the security of sha-256

[@dattaveerboda2405]

I'm not sure if I understood you correctly, but hashing is one way function, you can't reverse it, no way to reverse the text from Hash Value
