Open categoryTools for encoding, decoding, and converting text and binary data. Use Base64, Hex, URL Encode, Binary, ASCII, Unicode, JWT, and other formats online.
Open categoryExplore communication codes, symbolic alphabets, character substitution systems, and alternative text representations. Convert text using Morse code, A1Z26, Polybius Square, Bacon cipher, and other historical coding systems used for communication, education, puzzles, and secret messages.
Open categoryAnalyze text with frequency analysis, language statistics, and classical cryptanalysis tools. Study letter distributions, repeated patterns, n-grams, coincidence, entropy, and clues that help identify or break historical ciphers.
Open categoryGenerate hashes online with SHA-256, SHA-512, SHA-3, SHA-1, and MD5; create keyed HMAC values; and derive or verify password hashes with Argon2, bcrypt, and PBKDF2. All calculations run locally in your browser.
Open categoryGenerate UUIDs, secure random strings, passwords, and Diceware passphrases for development, testing, and everyday security. Choose the right format, create values in bulk, and work locally in your browser.
Open categoryShort explanations to help you choose the right tool.
Encoding changes a data format, encryption protects data with a key, and hashing creates a one-way digital fingerprint.
02Character patterns, repetition and text statistics help distinguish Base64, Morse code and classical ciphers.
03Substitution and transposition ciphers are useful for learning, puzzles and CTFs, but not for protecting modern data.
04SHA-256 checks data integrity, while bcrypt, Argon2 and PBKDF2 are designed for secure password storage.
