frequency-analysis

🛠️ Automate decryption and decoding with Ciphey, powered by AI and natural language processing for effective and efficient data analysis.

Standards-conformant acoustics library for Python: measurement and metrology, building, environmental and room acoustics, psychoacoustics, electroacoustics, vibration, underwater and aircraft/rotorcraft noise. Every method is implemented from the standard and validated against reference data, with teaching-style docs (formerly PyOctaveBand).

A little package developed with Go to make frequency analysis on text

NLP-приложение для подготовки иностранной лексики к изучению

Python and Jupyter Notebook implementations of nine practical experiments for ICT-4204 Mobile and Cellular Communication Laboratory, covering Doppler shift, frequency reuse, GSM, handover, path loss, cell coverage, and Erlang-B traffic analysis.

Classical shift cipher, then broken three ways with measured attacks

Interactive CLI tool for classical substitution cipher cryptanalysis based on Spanish letter frequency distribution.

Reproducible asteroseismology oscillation modes laboratory for simulation, scientific visualization, parameter exploration and quantitative analysis. Uses reproducible numerical experiments, parameter exploration and quantitative scientific visualization.

Fluent signal processing for Python, one line at a time.

Resonance is an open source project with two main parts. 1: Free-to-use web app for sound therapy. 2: A knowledge base markdown file compiled on 29 academic resource documents on sound frequencies and their therapeutic effects. Use it with any LLM for your own project!

Caesar cipher tool in C that breaks ciphertext by letter-frequency analysis (chi-squared, Euclidean and cosine distance).

An advanced, web-based interactive simulation suite for exploring Frequency Conversion Principles across Industrial Power Electronics (VFDs, Space Vector PWM), RF Telecommunications (Heterodyne Down/Up-converters, Image Rejection), and Digital Signal Processing (DSP).

⚡ Fast, zero-dependency Vigenère cipher in Node.js supporting Strings, Buffers, Streams, & Key Cracking.

Лабораторна робота №2 (Захист даних): шифр Енігми з CodinGame — 100% + повний криптоаналіз (4 атаки, частотний аналіз, індекс відповідності, оцінка простору ключів)

Лабораторна робота №3 (Захист даних): злам шифру Цезаря частотним аналізом — CodinGame 100% + порівняння правил рішення, IoC проти хі-квадрат, межі частотної атаки

Breaks substitution and Caesar ciphers using the letter and word statistics of English, with no key given.

Browser-based encrypted-database leakage demo — deterministic, order-preserving, and randomized ciphertexts side by side, with frequency-matching and sorting attacks scored cell by cell against the truth. The randomized control is put through the same query and the same attack, and the verdict is computed from what they measure.

Caesar cipher CLI in C: encrypt, decrypt, and break ciphers by letter-frequency analysis (chi-squared, Euclidean, cosine)

🛡️ CipherVault is a full-stack cryptography toolkit built with Python, FastAPI, React and Vite. It provides Caesar cipher encoding/decoding, statistical cryptanalysis, frequency analysis, 12+ hash algorithms, hash identification, HMAC/salt support, and educational hash recovery with real-time analysis and telemetry.

Browser-based Vigenère cipher demo — encrypt and decrypt with a repeating key, then recover the key length via Kasiski examination and index of coincidence and solve each column by frequency analysis. Real cryptanalysis. No backends. No simulated math.
