CipherTools – Offline Toolkit

Cyngus AB

À propos de l'application

CipherTools is a privacy-first offline utility app. Everything runs locally on your device — no internet connection, no accounts, no data collection of any kind.
🧮 Utility Tools
A clean calculator with full operator support, a multi-category unit converter (length, weight, temperature, speed), a text case converter (8 formats including camelCase and snake_case), and a random generator for numbers, strings, and UUID v4.
🔐 Security Tools
Generate SHA-256 hashes, encode and decode Base64, and encrypt or decrypt text using AES-256 (CBC mode). Your secret key is never stored or transmitted — it exists only in memory during your session.
📝 Text Tools
A lightweight notes editor with live word, character, and line counts. A detailed text analyzer (sentences, paragraphs, unique words). A text cleaner with configurable options to strip whitespace, line breaks, punctuation, digits, and non-ASCII characters.
