软件包摘要
Pseudorandom number sequence test program
历史
项目历史与用法
ent is John Walker's command-line program for applying statistical tests to byte streams, mainly to inspect pseudorandom number generators, compression output, encrypted data, and other files where information density matters.
项目历史
The official Fourmilab page describes ent as a pseudorandom number sequence test program that reads a file or standard input and reports entropy, optimum compression estimate, chi-square distribution, arithmetic mean, Monte Carlo value for pi, and serial correlation.
The page frames the tool around practical comparisons of generated data, including examples contrasting compressed files, Unix `rand()` output, an improved generator, and radioactive-decay random data from Fourmilab's HotBits service.
采用历史
ent is a small but widely repackaged scientific CLI. The input metadata lists it in Homebrew, Debian, Ubuntu, MacPorts, and Nix, reflecting its utility as a compact randomness and entropy smoke test in Unix-style workflows.
使用方式
Users run `ent` on a file or pipe data to standard input, optionally using flags for byte/bit-oriented output, counts, folding, terse CSV-style output, or stdin handling. The program is commonly used to sanity-check random generators, compressed data, encrypted data, and test fixtures.
为什么软件包爱好者会关心
ent is package-nerd friendly because it is tiny, public-domain in Homebrew metadata, scriptable, and easy to compare across systems. It gives quick statistical signals without requiring a larger cryptography or statistics suite.
时间线
- 1990s-2000s: Fourmilab page documents ent as a standalone pseudorandom sequence test utility.
- 2010s: Third-party GitHub mirror created for source availability, while Fourmilab remains the official documentation source.
- 2020s: Package metadata shows continuing availability in Homebrew and several Unix package collections.
Related projects
- The official page relates ent to Fourmilab HotBits, Unix `rand()`, Park-Miller style pseudorandom generators, and statistical references such as Knuth and Hamming.
