Why is MD5 still here if it's insecure?

MD5 is broken for security but useful for non-security checksums (file integrity, cache keys, dedupe). SHA-256 is the right choice when you need collision resistance.

Are the inputs uploaded?

No. Hashes are computed in your browser using WebCrypto (and a small inline MD5).

Can I hash large files?

Files load fully into memory first, so large files (>500 MB) may slow your browser. SHA-256 of a typical PDF is instant.

About Hash Generator (MD5, SHA-1, SHA-256, SHA-512)

Hash Generator computes cryptographic hashes (MD5, SHA-1, SHA-256, SHA-384, SHA-512) for any text or file. All five hashes update live as you type, or upload a file and get all of them at once for verification. Useful for verifying downloaded file integrity (compare against the publisher's published checksum), generating cache keys, hashing passwords for non-security uses, and confirming two files are identical. MD5 and SHA-1 are insecure for security purposes (collision attacks are trivial) but still useful for non-security checksums. Use SHA-256 or stronger for anything where collision-resistance matters. The SHA family is computed by the browser's WebCrypto API — the same hardened, audited implementation that powers TLS, Web Push, and Subresource Integrity. MD5 uses a small inline implementation because WebCrypto does not expose MD5 (and rightly so for security work, but it remains useful for legacy verification). Whether you're hashing a 12-byte string or a 500 MB file, the work happens on your CPU. Nothing uploads, no logs are kept, and the result is identical — bit for bit — to what tools like 'sha256sum' or 'openssl dgst' produce on Linux/macOS.

How Hash Generator (MD5, SHA-1, SHA-256, SHA-512) works

Type or paste text in the input area, or pick a file from your device.
All five hashes (MD5, SHA-1, SHA-256, SHA-384, SHA-512) compute simultaneously.
For text, hashes update live as you type. For files, the entire file streams through WebCrypto in a single pass.
Each hash displays in standard lowercase hex. Click to copy.
Compare with a published checksum to verify a download, or compare two computed hashes to confirm two files are identical.

When to use Hash Generator (MD5, SHA-1, SHA-256, SHA-512)

Verify a downloaded ISO, installer, or archive matches the publisher's published SHA-256 checksum.
Generate a cache key from a long input (a URL, a config blob) so that identical inputs always produce the same key.
Confirm two files are byte-identical without a manual diff (useful for backup verification).
Generate idempotency keys when an API needs deterministic IDs from variable input.
Audit data integrity by recomputing hashes from a backup and comparing against original manifests.
Compute CRC-style fingerprints for deduplication when storing user uploads.

Why choose Utilix Hash Generator (MD5, SHA-1, SHA-256, SHA-512)

All five common hashes in one place — no need to bounce between separate MD5 and SHA-256 tools.
WebCrypto-backed SHA hashes are produced by the browser's audited cryptographic implementation.
Local-only — file hashing never uploads, so it's safe for confidential or large files.
Output matches sha256sum/openssl exactly, so you can cross-verify with command-line tools.
No daily limits, no sign-up, and no ads slowing the page down.
