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 […]
Passwords should never be stored as plain text. Whether we are talking about a web application or an operating system, they should always be in the hash form (on Linux, for example, hashed passwords are stored in the /etc/shadow file). Hashing is the process through which, by the use of complex algorithms, a password is […]
