How do I generate an MD5 or SHA-256 hash of text or a file?

Type text or drop a file into AnyTool's Hash Generator and it computes MD5, SHA-1, SHA-256, SHA-512, CRC32, and HMAC at once. Hashing uses WebCrypto and hash-wasm in your browser, so files are never uploaded.

  • MD5, SHA-1/256/384/512, SHA-3, CRC32, and HMAC together
  • Hash text live or drag-and-drop large files with progress
  • Compare against an expected checksum; hex/UPPER/Base64 output
  • 100% in your browser — no upload, no signup, free

What is

Hash Generation

Hash generation runs a one-way function over text or a file to produce a fixed-length digest (such as SHA-256) used for integrity checks, checksums, and signatures. HMAC adds a secret key for authenticated hashing.

How to Generate a Hash

Compute cryptographic hashes of text or files entirely in your browser.

10 secWeb browser
  1. 1

    Add input

    Type or paste text, or drag and drop a file (hashed in chunks with progress).

  2. 2

    Read the digests

    See MD5, SHA-1/256/512, CRC32, and HMAC computed together in your chosen format.

  3. 3

    Verify or copy

    Paste an expected checksum to verify, or copy any digest with one click.

Result: Hash digests for text or a file

Frequently Asked Questions

No — files are hashed entirely in your browser and never uploaded.

AnyTool computes hashes locally using the browser's WebCrypto API and hash-wasm. Files are read in chunks on your device, so nothing is sent to a server and there is no VirusTotal or third-party lookup.

MD5, SHA-1, SHA-256, SHA-384, SHA-512, SHA-3, CRC32, and HMAC variants.

All common algorithms compute at once: cryptographic hashes (MD5, the SHA-1/2/3 families), the CRC32 checksum, and keyed HMAC digests — with output as lowercase hex, uppercase hex, or Base64.

Yes — paste an expected hash and it shows an instant match or no-match indicator.

Enter the checksum you expect and the tool compares it (case-insensitive, whitespace-trimmed) against every computed digest, so you can verify a download or file integrity in one step.

Detailed Explanation

Methodology

How Hash Generation Works

AnyTool computes hashes using the browser's WebCrypto API for the SHA-2 family and hash-wasm for MD5, CRC32, SHA-3, and HMAC, which WebCrypto cannot provide. Text is hashed live; files are read in chunks (not loaded whole into memory) and hashed with a progress indicator, so large files stay responsive. Output is available as lowercase hex, uppercase hex, or Base64, and a verify field compares against an expected checksum. Everything runs locally — files are never uploaded.

  • WebCrypto + hash-wasm: MD5, SHA-1/256/384/512, SHA-3, CRC32, HMAC
  • Chunked/streaming file hashing with progress
  • Hex, UPPERCASE hex, and Base64 output
  • Checksum verify with instant match/no-match
  • No upload and no third-party (e.g. VirusTotal) lookups
