Hashing & Checksums Tools
Free online hashing tools — generate SHA-256 hashes from text or hex bytes, with SHA-512, MD5, HMAC and bcrypt generators next. All run in your browser.
Hashing & Checksums tools
Why These Tools
SHA-256 is everywhere. Git uses it for every object ID. npm uses it to verify package integrity. JWT signatures depend on it. TLS certificate fingerprints are printed as it. And yet there is rarely a clean browser-based tool that lets you check what SHA-256 of a specific string or a specific set of bytes actually is, without uploading anything anywhere.
The SHA-256 Hash Generator starts this category: type text or paste hex bytes and the digest appears instantly in hex, Base64 or Base64URL. SHA-512, MD5, BLAKE2, HMAC-SHA256, bcrypt and Argon2 come next. Every one runs entirely in the browser using the Web Crypto API, so no plaintext credential ever leaves your tab.
