Essential developer utility tools

1. Crypto & Security Tools Crucial for authentication setup, payload verification, and security testing. JWT Parser / Decoder: Decodes JSON Web Tokens ( Header , Payload , and Signature ) without transmitting secret keys over the internet. Token & Password Generator: Generates cryptographically secure random passwords and API tokens with customizable character sets, lengths, and complexity rules. Hash Text Generator: Computes cryptographic hashes (MD5, SHA-1, SHA-256, SHA-512) for strings to verify integrity or check signature matching. Bcrypt Hash / Verifier: Hashes plain-text passwords or checks plain text against an existing hash using the bcrypt algorithm. UUID / ULID Generator: Creates universally unique identifiers (v4 UUIDs) or time-sortable lexicographically sortable unique identifiers (ULIDs). BIP39 Mnemonic Generator: Generates seed phrases and cryptographic keys used in wallet initialization and HD key generation. RSA Key Pair Generator: Generates public and private RSA key pairs directly in the browser for local testing of asymmetric encryption systems. Basic Auth Generator: Quickly constructs Authorization: Basic <base64> HTTP header credentials from a username and password. 2. Formatters & Prettifiers (Development) Saves hours when dealing with messy logs, API responses, or raw system configurations. JSON Prettify & Minify: Formats unformatted API JSON strings with customizable indentation or compresses them into a single line to reduce payload sizes. JSON Diff: Highlights additions, deletions, and structural changes between two JSON payloads. SQL Prettify: Formats raw SQL queries into clean, readable multi-line statements with capitalized keywords. YAML / XML Formatter: Cleans up indentation, validates structure, and formats raw XML and YAML files. Docker Run to Docker Compose: Translates single CLI flags ( docker run -d -p 80:80 ... ) into a structured docker-compose.yml file. Cron Expression Generator & Parser: Provides human-readable schedules from
