Cryptographic Hashes & Developer Test Generators
Essential online utilities for web developers, software engineers, and QA testers requiring mock data and secure tokens.
1. Crypto PRNG Passwords
Uses browser crypto.getRandomValues() for cryptographically secure pseudo-random number generation.
2. Web Crypto API SHA-256
Computes 256-bit hash digests locally using native crypto.subtle.digest.
3. Mock UI Placeholder Text
Generate customizable paragraphs of standard dummy text for UI design mockups and layout prototyping.
About the Generators
The Generators panel collects the throwaway values developers need constantly: strong random passwords with configurable length and character sets, RFC 4122 UUIDs for test fixtures and primary keys, SHA and MD5 hashes for checksums, and lorem ipsum paragraphs for filling a layout. Randomness comes from the Web Crypto API, so generated secrets are cryptographically secure rather than derived from Math.random.
How to use the Generators
- Pick the generator you need: password, UUID, hash or lorem ipsum.
- Adjust the options such as length, character set or hash algorithm.
- Copy the generated value.
Frequently asked questions
Are the generated passwords actually secure?
Yes. They use crypto.getRandomValues, the browser cryptographically secure random source, rather than Math.random. Values are generated on your device and never transmitted, so no server ever sees them.
Should I use MD5 for passwords?
No. MD5 and SHA-1 are broken for security purposes and are only appropriate as non-security checksums. Store passwords with a dedicated password hashing function such as bcrypt, scrypt or Argon2.
Which UUID version is generated?
Version 4, which is random rather than time or namespace based. It is the right default for identifiers that must be unguessable and can be created independently by different services.
