Create cryptographically secure, high-entropy passwords and API secret keys using the Web Cryptography API random number generator.
A password's strength is measured in bits of entropy. A 16-character password containing lowercase, uppercase, numbers, and symbols possesses over 90 bits of entropy.
Such passwords require billions of years to crack with modern supercomputer clusters.
We use window.crypto.getRandomValues(), the browser's cryptographically secure pseudo-random number generator (CSPRNG).
Compute 256-bit (64 hex characters) cryptographic hash checksums for any input string using browser-native Web Crypto APIs.
Calculate 32-character hexadecimal MD5 hash checksums for cache busting, database keys, and file integrity verification.
Generate standard RFC 4122 compliant version 4 UUIDs (Universally Unique Identifiers) for database primary keys, distributed systems, and API tracking.
Decode Base64Url encoded JWTs to inspect authentication headers, payload claims (iss, sub, exp), and verify token expiration in real-time.
