>      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. Over time however, this
>    requirement can fail due to attacks on the mathematical
>    underpinnings of hash functions or to increases in
>    computational power.
