Hash & Checksum Generator Tools
Free browser-based hash generators covering MD2-MD6, the full SHA-1/2/3 and SHAKE families, CRC-16/32, Whirlpool, and password-specific formats like NTLM and WordPress phpass.
Built for developers, by a developer.
All tools run locally in your browser. Your data never leaves your device.

Why this collection exists
Generate a hash digest from arbitrary text using any common algorithm — from legacy MD2 and MD4 for compatibility checks, through MD5, the full SHA-1/SHA-2/SHA-3 families and SHAKE extendable-output functions, to CRC-16/32 checksums and 512-bit Whirlpool. Two tools generate a password hash in a specific storage format instead — NTLM (MD4 over UTF-16LE password bytes) and WordPress-compatible phpass — since a password hash needs to match a particular system's exact format, not just any digest algorithm.
Every hash is computed locally in your browser. Nothing you type is ever uploaded or logged.
Best fit for
- Developers verifying file or message integrity with a checksum
- Security researchers checking a value against known legacy hash formats (MD2/MD4/MD5)
- Systems administrators generating an NTLM hash for password auditing or compatibility testing
- WordPress developers generating a phpass hash for direct database seeding or migration testing
- Students and engineers comparing output length and format across the MD, SHA, and SHA-3 families

Collection FAQ
Extra context around when to use this toolkit and where to start.
Which hash algorithm should I use for a new project?
For general integrity checks, SHA-256 is the current standard. MD5, MD4, MD2, and SHA-1 are included for legacy compatibility and verification, not for new security-sensitive use — they are cryptographically broken for collision resistance.
Why are NTLM and WordPress password hashing separate from the other hash tools?
A generic hash tool (like SHA-256) hashes whatever text you give it once. NTLM and phpass are specific storage formats used internally by Windows authentication and WordPress respectively — matching their exact algorithm and encoding is the point, not choosing a hash strength.
Is any text or password I enter uploaded or stored?
No. All hashing happens locally in your browser using standard Web Crypto or in-browser algorithm implementations — nothing is sent over the network.
