Free Hash Generator for MD5 and SHA
Paste text or upload a file and get its MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes at once, each with its own copy button. It runs entirely in your browser, so nothing you hash is uploaded.
Enter text or upload a file to see every hash
MD5 and SHA-1 are fine for checksums, cache keys and deduplication, but they are broken for security. For passwords, signatures or anything an attacker could tamper with, use SHA-256 or stronger.
Handy for checksums, cache keys and verifying downloads. For passwords and signatures, use a proper security library, not MD5 or SHA-1.
Every hash in four steps.
Paste text or upload a file, watch all five hashes appear together, pick your hex format, then copy the one you need.
Paste or upload
Type or paste your text into the box, or upload a file. Everything is read and hashed on your own device.
Get every hash at once
MD5, SHA-1, SHA-256, SHA-384 and SHA-512 all appear together, one row per algorithm, updating as you type.
Pick your format
Flip between lowercase and uppercase hex with one toggle, so the output matches whatever the other side expects.
Copy the one you need
Every row has its own copy button. Tap it and paste the hash into your config, script or checksum comparison.
A hash tool that is straight with you.
Five algorithms, text and files, and plain words about which hashes are safe for security work and which are only for checksums.
Five algorithms at once
No dropdown to fiddle with. One input gives you MD5, SHA-1, SHA-256, SHA-384 and SHA-512 side by side, each with its own copy button.
Text and files, one tool
Hash a quick string or a whole file. Uploads are read locally and hashed byte for byte, so the result matches command line tools like md5sum and sha256sum.
Honest about MD5 and SHA-1
MD5 and SHA-1 are broken for security, so never use them for passwords or signatures. They are still perfectly fine for checksums, cache keys and deduplication, which is why they are here.
Private by design
Everything runs in your browser. Nothing you type or upload is sent to a server, so you can safely hash private files and internal data.
Verification that runs on its own.
A hash page covers the quick check. But if your team verifies every upload, deduplicates documents, or signs and audits files as part of daily work, that logic belongs inside your own software, running automatically instead of by hand. That is the kind of custom tooling and integration work we build at Techliphant, shaped around how your business actually runs.

Common questions.
A hash is a short, fixed-length fingerprint calculated from any input, whether that is three words or a three gigabyte file. The same input always produces the same hash, and even a one character change produces a completely different one. That makes hashes useful for spotting changes, verifying downloads and indexing data.
For anything security related, use the SHA-2 family: SHA-256 is the everyday default, and SHA-384 or SHA-512 give longer digests where a standard demands them. MD5 and SHA-1 are older and faster, and today they belong in non-security jobs like file checksums, cache keys and deduplication. If a system you are integrating with asks for a specific algorithm, match what it asks for.
Researchers can deliberately craft two different inputs that produce the same MD5 or SHA-1 hash, which is called a collision. That breaks them for signatures, certificates and anything an attacker might tamper with. It does not affect their everyday use as checksums: for catching accidental corruption or finding duplicate files, they still work fine and are widely used.
Many download pages publish a checksum, usually SHA-256, next to the file. Upload your downloaded copy here, and compare the hash shown with the one on the page. If they match character for character, the file arrived intact and is the file the publisher intended. If they differ, delete it and download again.
No. A hash is a one-way calculation, and the original data is not inside it. A 64 character SHA-256 hash can stand for an input of any size, so there is no way to unfold it back into the source. The only so-called reversal is guessing: trying inputs until one produces the same hash, which is why weak passwords with fast algorithms are guessable but the hash itself never gives anything away.
Hash algorithms are deterministic by design: the same bytes in, the same digest out, on any machine, in any language, forever. That is the whole point. It lets two sides compare fingerprints without exchanging the data itself. Note that hashing works on bytes, so "abc" and "abc " with a trailing space are different inputs with completely different hashes.
Yes, that is exactly what this tool does. When you pick a file, your browser reads it locally and computes every hash on your own device. It never leaves your machine, so hashing works even for private documents and internal builds. Files up to tens of megabytes hash in a moment.
No. The whole tool runs in your browser using JavaScript and the built-in Web Crypto API. There is no upload, no storage and no logging, and it keeps working on the page even if your connection drops after it loads.
Yes. A page like this covers a quick check, but if your team verifies uploads, deduplicates documents or signs and audits files as part of daily work, that logic belongs inside your own software. That is the kind of custom tooling and integration work we do at Techliphant.
Private by design: this hash generator runs entirely in your browser, so nothing you type or upload is sent anywhere or stored. Your text and files stay on your own device. It is provided free for quick checksums and everyday use.
