Checking a hash usually means picking an algorithm first and hoping it’s the right one. Our new Hash Generator skips that guesswork and computes all four at once.
- Four algorithms, one input — MD5, SHA-1, SHA-256, and SHA-512 update together, live, as you type. Compare them side by side instead of running the same text through four separate tools.
- A hand-verified MD5 — Web Crypto’s SubtleCrypto API doesn’t implement MD5 (it’s deprecated at the browser-standard level), so this tool ships its own RFC 1321 implementation, checked against the standard test vectors before launch.
- Native everywhere else — SHA-1, SHA-256, and SHA-512 run through
the browser’s own
crypto.subtle.digest(), the same code path used by security-sensitive applications. - One-click copy — grab any single digest without selecting text by hand.
- Private by default — every digest is computed in your browser; nothing you type is ever sent to a server.
Paste in a string and watch the avalanche effect firsthand: change one character and all four outputs come out unrecognizable. If you need hash generation inside your own docs site or internal tool, it’s embeddable with one iframe.
