How to Use This Hash Generator

Workflow

  1. Choose between Text, File, Compare, or HMAC tabs.
  2. Toggle between Hex and Base64 output formats at the top right.
  3. For files, drag and drop the file into the browser. Hashes generate instantly.
  4. For HMAC, enter your message and secret key to generate a signed hash.

Modern Use Cases

  • SHA-256 / SHA-3: The current industry standard for SSL, passwords, and blockchain.
  • Base64 Format: Required for JWT (JSON Web Tokens) and many modern REST APIs.
  • RIPEMD-160: Commonly used in Bitcoin address generation.
  • MD5 / SHA-1: Avoid for security. Use only for legacy file checksums or Git.

About This Tool

The Hash Generator is a free online tool that instantly converts any text or file into a secure, fixed-length string of characters.

Whether you are a developer verifying that a downloaded file hasn't been tampered with, checking if two sets of data are identical, or generating a unique digital fingerprint, this tool gives you the exact MD5, SHA1, SHA256, and SHA512 hashes you need.

Simply type your text or upload a file, and the hashes are calculated instantly. Because everything runs locally in your browser, your sensitive data and files are never uploaded to a server.

How to Use

  1. 1Type or paste the text you want to hash into the input box (or upload a file).
  2. 2View the four different hash values (MD5, SHA1, SHA256, SHA512) generate instantly as you type.
  3. 3Click the "Copy" button next to the specific hash algorithm you need.
  4. 4If you are checking a file, compare the generated hash to the one provided by the website where you downloaded the file.
  5. 5If the two hashes match exactly, your file is safe and uncorrupted.

Frequently Asked Questions

A hash acts as a unique digital fingerprint for a piece of data. It is commonly used to verify file integrity (making sure a downloaded file wasn't corrupted or hacked) and to securely store passwords in databases without keeping the actual plain-text password.

Encryption is a two-way street; you can encrypt data and then decrypt it later if you have the key. Hashing is a one-way street. Once you turn text into a hash, it is mathematically impossible to reverse the process and turn the hash back into the original text.

No. Because hashing is a one-way mathematical function, you cannot decode a hash back into its original text. You can only take new text, hash it, and see if the new hash matches the old one.

For modern security purposes, SHA256 or SHA512 are strongly recommended because they are highly secure. MD5 and SHA1 are older and considered vulnerable to attacks, but they are still commonly used for non-security tasks like checking if files are identical.

Yes. All hash generation happens directly inside your web browser using JavaScript. Your text and files are never uploaded to our servers, ensuring your private data remains completely secure.
