Security & Hash Tools
Generate secure MD5, SHA-256, SHA-512 hashes, cryptographically secure passwords, UUID v4 tokens, and inspect JWT headers.
SHA-256 Hash Generator
Compute 256-bit (64 hex characters) cryptographic hash checksums for any input string using browser-native Web Crypto APIs.
MD5 Hash Checksum Generator
Calculate 32-character hexadecimal MD5 hash checksums for cache busting, database keys, and file integrity verification.
Strong Password Generator & Entropy Checker
Create cryptographically secure, high-entropy passwords and API secret keys using the Web Cryptography API random number generator.
UUID v4 Generator (Single & Bulk)
Generate standard RFC 4122 compliant version 4 UUIDs (Universally Unique Identifiers) for database primary keys, distributed systems, and API tracking.
JWT (JSON Web Token) Debugger & Inspector
Decode Base64Url encoded JWTs to inspect authentication headers, payload claims (iss, sub, exp), and verify token expiration in real-time.
SHA-512 Cryptographic Hash Generator
Compute 512-bit (128 hexadecimal characters) SHA-2 family hashes for mission-critical checksums, blockchain verification, and token verification.
