5 algorithms + HMAC + file hashing + compare, all in browser.
A hash generator computes a fixed-size cryptographic fingerprint from any text or file. This tool runs five algorithms (MD5, SHA-1, SHA-256, SHA-384, SHA-512) plus HMAC for authenticated hashes. The SHA-2 family uses the browser's native Web Crypto API for speed; MD5 ships as a pure-JS implementation since Web Crypto doesn't include it.
Most online hash tools support 1-2 algorithms and ship single-input mode. We support five algorithms side-by-side, file hashing, HMAC signing, and side-by-side hash comparison. Browser-only, no upload, no signup.
Most generators show one algorithm at a time. We show all five so you can pick after seeing what you get.
JWT signing, API request signing, webhook verification. Most free tools skip HMAC entirely.
Some online hashers refuse files larger than a few MB. We handle ~100MB locally with no upload.
Input often includes secrets (HMAC keys, sensitive payloads). We never see them. md5hashgenerator.com sends inputs to their server.

Yes. Unlimited use, no signup, browser-only. md5hashgenerator.com is free but ad-supported and ships single algorithms; we ship five plus HMAC and file hashing.
Five: MD5, SHA-1, SHA-256, SHA-384, SHA-512. SHA-2 family runs via the browser's Web Crypto API (fast, native). MD5 runs via a pure-JS implementation since Web Crypto doesn't include it.
No. MD5 is cryptographically broken -collisions can be generated cheaply. Don't use it for password storage, signatures, or any security-sensitive context. It's still fine for non-security uses like file integrity checksums or cache keys.
Not for security. SHACK1 was broken in 2017 (Google's SHAttered attack found a real collision). Migrate any SHA-1 signatures or HMACs to SHA-256 or stronger. SHA-1 is only acceptable for non-security checksums.
Hash-based Message Authentication Code. Combines a hash function with a secret key to produce an authentication tag. Used in JWT signatures (HS256 = HMAC-SHA-256), API request signing, webhook verification. We support SHA-1 / SHA-256 / SHA-384 / SHA-512 HMAC.
Yes. Drop the file, pick the algorithm, get the hex digest. Used for verifying downloaded files match the publisher's checksum, deduplicating files by content, content-addressable storage.
Up to about 100MB depending on browser memory. The whole file gets read into memory before hashing. For multi-GB files, use a streaming CLI tool like `sha256sum`.
No. All hashing happens via Web Crypto (subtle.digest) or the bundled MD5 implementation. Your text or file bytes never leave the page. Some online hash tools log inputs for analytics; we don't run any server endpoints.
Yes via the side-by-side view. Useful when downloading software and comparing your computed hash to the publisher's posted hash. Mismatch means the file was tampered with or corrupted in transit.
They shouldn't. If they do, check for trailing whitespace, line ending differences (LF vs CRLF), or character encoding (UTF-8 vs Latin-1). The same logical text can have different byte sequences which produce different hashes.
5 algorithms, HMAC, file hashing, compare. Free unlimited.
