Hash Generator

What is this tool?

A free hash generator that computes MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes from text or a file you provide. It's built for developers and anyone who needs to quickly generate or verify a hash without installing command-line tools.

When to use it

  • Generating a checksum to verify text content hasn't changed
  • Testing how different hashing algorithms handle the same input
  • Creating a hash for use in a script, config file, or test case
  • Comparing a hash you received against one generated from the original text
  • Learning the difference between MD5, SHA-1, and SHA-2 family hashes

How to use it

  1. 1Open the Hash Generator tool.
  2. 2Enter or paste the text you want to hash, or choose a file.
  3. 3View the generated MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes.
  4. 4Copy the specific hash you need.
  5. 5Use it to verify integrity, populate a config, or compare against another hash.

Frequently asked questions

Is MD5 still safe to use for security purposes?

MD5 and SHA-1 are considered weak for security-sensitive applications like password storage; SHA-256 or higher is generally recommended for those cases. This tool provides MD5 mainly for compatibility and checksum purposes.

Does this tool hash files, or only text?

Both. Type or paste text, or choose a file — a file is read and hashed in your browser and never uploaded.

Is my text sent to a server to compute the hash?

No, hashing happens entirely in your browser using JavaScript and the Web Crypto API.

Why do I get a completely different hash from a tiny text change?

This is expected — cryptographic hash functions are designed so that even a one-character change produces an entirely different output.

Can I generate multiple hash types from the same input at once?

Yes, the tool computes MD5, SHA-1, SHA-256, SHA-384, and SHA-512 from the same text simultaneously.
