I know that collision for MD5 has been documented since the 90s and that digital certificates based off of MD5 has been demonstrated to be completely compromised back in 2010 but how effective is MD5 in ensuring that small amounts of data … Continue reading Is it secure to use MD5 to verify the integrity of small files (less than 15kb)?
I’ve heard that there is a string that contains only the letters a to z whose MD5 hash begins with the hexadecimal prefix 314159265358 and the rest can be arbitrary. How can one find such a string and how long would the searc… Continue reading How one can find a string whose MD5 hash has a specific prefix?

I’m a rookie when it comes to Information Security so I’ve been reading a lot of the top questions on this stackexchange for the sake of learning. I came across this question that discusses hashing. In criticism of a home-b… Continue reading Rearranging hash adds no security?
I’m making a program to compare all the files on a 3Tb drive by hash and delete duplicates. I was initially going to use MD5, but was worried that with 3Tb of files, there was a slight chance of a collision that would cause a… Continue reading Would using both SHA1 and MD5 hashes of files help reduce the risk of deleting non duplicates
