Complete Encoder/Decoder and Encryption Tool CryptiCode: Comprehensive Encryption, Encoding, and Conversion Toolkit Whether you are a developer, a security enthusiast, a student, or just someone who occasionally needs to transform data, CryptiCode brings a full suite of cryptographic, encoding, and conversion tools directly into your browser. All operations run locally, so your information stays private, and you can work offline without any interruptions. The extension is organized into ten clearly labelled sections, making it easy to find exactly what you need. You can switch between light and dark themes, choose from over twenty interface languages, and copy any result with a single click. Number Base Converter – Quickly translate numbers between binary, octal, decimal, and hexadecimal. The tool automatically detects the base of your input (for example, 0x for hex), saving you time and reducing errors. This is invaluable for programmers dealing with memory addresses, colour codes, or low‑level data. Bitwise Operations – Perform AND, OR, XOR, NOT, popcount, and parity calculations on integers. The results are shown both as decimal values and in binary form, helping you understand the bit‑level logic behind your computations. Encoders and Decoders – This section covers a wide range of text transformations: Base64, hexadecimal, URL encoding, Base32, Base58, HTML entities, UTF‑8 to hex, Unicode escape sequences, and quoted‑printable. An intelligent auto‑detection feature highlights the most likely decoding action based on your input, so you never have to guess which format you are dealing with. Hashing Algorithms – Generate cryptographic hashes using MD5, SHA‑1, SHA‑256, SHA‑512, SHA‑3, BLAKE2b, and CRC32. For authenticated message integrity, HMAC‑SHA256 and HMAC‑SHA512 are also available. These functions are essential for file integrity checks, password storage, and digital signatures. Symmetric Encryption – Encrypt and decrypt text with AES (supporting CBC, ECB, CFB, OFB, and CTR modes), DES, RC4, and the modern ChaCha20‑Poly1305. The tool automatically generates and embeds the initialisation vector where needed, simplifying the process while maintaining strong security. Asymmetric Encryption – Generate RSA key pairs (2048 bits) and use them to encrypt messages with the public key and decrypt them with the private key. This is ideal for secure key exchange and digital signing. File Hashing – Select any file from your system and compute its hash using the same algorithms available for text. The file never leaves your device, ensuring complete confidentiality. Text Analysis – Obtain detailed statistics about any text: character count, Unicode code points for each character, and the byte representation in UTF‑8. This is particularly useful when debugging encoding issues or when you need precise length measurements. Value Comparison – Compare two or more strings character by character. Differences are highlighted in red and similarities in green, with spaces visually marked. This makes it easy to spot even subtle changes between data sets. Auto‑Detect – Paste any unknown string, and CryptiCode will attempt to identify its type—whether it is Base64, hex, a number in any base, URL‑encoded, JSON, an ISO date, or plain text. It then presents useful metadata about the detected format. Privacy and Performance – All processing occurs inside your browser using native Web Crypto APIs and lightweight libraries. No data is ever sent to any server, and the extension requires only the storage permission to remember your preferences. It is fast, responsive, and consumes minimal system resources. Customisation and Accessibility – The interface adapts to your system’s colour scheme or lets you choose manually between light and dark modes. With support for over 20 languages, users from all regions can work comfortably. Every output field includes a copy button for quick reuse. CryptiCode is completely free, contains no ads, and has no in‑app purchases. It is designed for everyone—from professionals needing reliable cryptographic tools to curious learners exploring data transformation concepts. Install it once, and you will always have a versatile Swiss Army knife for your data right at your fingertips. Start using CryptiCode today and experience the convenience of having a complete cryptographic and encoding workstation built into your browser.
