What is Hash Generator?

Hash Generator converts text or files into fixed-length digest values such as MD5, SHA-1, SHA-256, and SHA-512. It is useful for checksum comparison, file verification, and quickly understanding how different hash algorithms produce different outputs for the same input.

How to Use Hash Generator

  1. Enter text or switch to file mode and choose a file.
  2. Let the tool calculate the available hash algorithms in parallel.
  3. Review the digest values you need for checksum comparison or record keeping.
  4. Copy the required hash for verification, scripting, or documentation.

  • Compare MD5, SHA-1, SHA-256, and SHA-512 output for the same input
  • Generate fingerprints for deduplication, caching, or asset tracking
  • Check hash values locally before publishing or sharing files
Why Use This Tool
  • Useful for checksum verification, release artifacts, and integrity checks.
  • Shows several common algorithms at once for quick comparison.
  • Processes text and files locally in the browser without uploading them.
Frequently Asked Questions
Is MD5 still safe to use?

Not for security purposes. MD5 is broken for collision resistance. Use SHA-256 or SHA-512 for integrity checks, and bcrypt/argon2 for passwords.

Can I hash a file?

Yes. Switch to the File tab, drop your file, and all four algorithms will compute the hash instantly.

Is my file uploaded?

No. File hashing uses the browser's FileReader and Web Crypto APIs. Nothing leaves your device.

What is the difference between MD5, SHA-1, SHA-256, and SHA-512?

They differ in digest length and security level. MD5 produces 128-bit (32-char) hashes: fast but cryptographically broken. SHA-1 produces 160-bit (40-char) hashes and is also deprecated for security use. SHA-256 and SHA-512 are part of the SHA-2 family and remain secure for integrity checking and digital signatures.
