Hash Generator
Paste any text and get all five common digests at once — MD5, SHA-1, SHA-256, SHA-384 and SHA-512 — as lowercase hex, each with its own copy button. The SHA family is computed by your browser's native Web Crypto engine. Nothing is uploaded to Filesvo.
Processed on your device — files are never uploaded to Filesvo.
How to use Filesvo
- Type or paste the text to hash.
- Click Compute hashes.
- Copy the digest you need from the results.
Which hash should you use?
A hash is a fixed-length fingerprint of your input: the same text always produces the same digest, and any change — even one character — produces a completely different one. The text is encoded as UTF-8 first, so results match what command-line tools like sha256sum produce for the same text.
For anything security-related — passwords, signatures, integrity checks against tampering — use SHA-256 or stronger. MD5 and SHA-1 are cryptographically broken (collisions can be manufactured) and are included here only because legacy systems and checksums still use them; the tool labels them accordingly.
Private by design
Your files are processed directly in your browser using the browser's built-in APIs and are not uploaded to Filesvo. Nothing is stored on our servers, because nothing ever reaches them.
Frequently asked questions
- Why does my hash differ from another tool's?
- Almost always a trailing newline or different encoding. This tool hashes exactly the text in the box as UTF-8, with nothing added. Command-line tools like echo often append a newline, which changes the digest completely.
- Can a hash be reversed to get my text back?
- No — hashing is one-way. But short or common inputs can be guessed by brute force, which is why passwords need salted, slow hashing (bcrypt, argon2) rather than any of these plain digests.
- Why are MD5 and SHA-1 marked 'not for security'?
- Both have practical collision attacks — different inputs can be crafted to share the same digest — so they can't guarantee integrity against a deliberate attacker. They remain fine for detecting accidental corruption and matching legacy checksums.
- Is my text sent to a server?
- No. All hashing runs in your browser — the SHA family via the native Web Crypto API — and your text never leaves your device.
