Understanding Bitcoin is a one-way hash function should make sense because a hash function cannot be reversed. Once you understand that, it is hard to go back to thinking otherwise. The secure hash ...

But there it's not applied as a security measure. For integrity it doesn't really matter, the only issue there is a random collision and that's still as unlikely as ever. It's pretty much impossible ...

Security researchers have achieved the first real-world collision attack against the SHA-1 hash function, producing two different PDF files with the same SHA-1 signature. This shows that the algorithm ...
