Il team di ricerca di Google ha annunciato la tanto attesa "rottura" dell'algoritmo di hashing SHA1, dimostrata empiricamente mostrando la prima collisione pubblica di due documenti PDF.
Cryptographic hash functions like SHA-1 are a cryptographer’s swiss army knife. You’ll find that hashes play a role in browser security, managing code repositories, or even just detecting duplicate files in storage. Hash functions compress large amounts of data into a small message digest. As a cryptographic requirement for wide-spread use, finding two messages that lead to the same digest should be computationally infeasible.
