What is Hash Generator?

A cryptographic hash function takes any input — text or a file of any size — and produces a fixed-length output (the hash or digest) that is unique to that input. Even a single character change produces a completely different hash. This tool generates MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes using your browser's Web Crypto API, meaning the data never leaves your device. Note that MD5 and SHA-1 are considered cryptographically broken and should not be used for security purposes — use SHA-256 or stronger.

How to use this tool

  1. 1 Choose 'Text' or 'File' input mode using the toggle.
  2. 2 For text: type or paste your input — all hash variants update instantly as you type.
  3. 3 For files: click 'Choose file' to select any file — the hash is computed locally without uploading.
  4. 4 Copy the hash you need by clicking the copy icon next to it.
  5. 5 Use SHA-256 or SHA-512 for security-sensitive applications; MD5 is only appropriate for checksums where collision resistance is not required.

When would you use this?

  • Verifying a downloaded file's integrity by comparing its SHA-256 hash against the one published by the software vendor.
  • Generating a deterministic identifier from a string — for example, hashing an email address to create a Gravatar URL or an anonymised user ID.
  • Checking whether two files are identical without opening them — if their SHA-256 hashes match, the files are byte-for-byte identical.

How Hash Generator works

  1. 1

    Type text or drop a file

    Switch between Text mode (paste any string) and File mode (drop or browse any file). Hashes update live as you type in Text mode.

  2. 2

    Select the algorithms you need

    Choose any combination of MD5, SHA-1, SHA-256, SHA-384, and SHA-512. For security use SHA-256 or stronger — MD5 and SHA-1 are cryptographically broken.

  3. 3

    Copy in your preferred encoding

    Output is available in Hex (lowercase), Base64, or Base64URL (URL-safe, no padding). Click any row to copy that specific hash, or "Copy all" for all at once.

Looking for a free SHA-256 hash generator online, or need to compute an MD5 or SHA-512 checksum? Hashing turns any input — a string, a file, a password — into a fixed-length fingerprint. SHA-256 is the current standard for file integrity checks, API request signing (HMAC-SHA256), and certificate fingerprints. MD5 is still used for non-security checksums like cache busting and legacy database fields — but should never be used for passwords or digital signatures. This tool computes all five algorithms simultaneously so you can compare outputs and pick the right one.
