This simple tutorial shows how to install the most recent xxHash for faster hash checking in Ubuntu Linux.
xxHash is extremely fast non-cryptographic hash algorithm, working at RAM speed limit. It can be useful to check integrity for large amounts of data, index data, and/or used in cryptographic applications like digital signatures.
The library includes the following algorithms:
- XXH32 : generates 32-bit hashes.
- XXH64 : generates 64-bit hashes.
- XXH3/XXH128 (since v0.8.0): generates 64 or 128-bit hashes, using vectorized arithmetic.
I’m new to hash algorithm, but doing hash check regularly when trying out different Linux distributions. And I use sha256, since the most sites provide sha256sum files for the hash code of their disco images.
