$MD5 Length: 32 characters
$Warning: MD5 has known collision vulnerabilities. Do not use for password storage or security authentication. Use SHA-256 or stronger.

About this tool

Generate MD5 hashes, compare two MD5 results, and create random passwords with instant MD5 output in one simple browser tool.

  • Your input never leaves the browser
  • Handles large files and batch input
  • Customizable formatting and indent options
  • Free and unlimited, no sign-up

Compared with IDE plugins or CLI tools

Aspect This tool Typical alternative
Iteration speed Better for quick paste-and-check loops Deeper integration, heavier startup
Sharing Easier to share samples and outputs Better for longer engineering workflows
Environment dependency Only needs a modern browser Often depends on editor and local setup

Docs

Generate MD5 hashes, compare two MD5 results, and create random passwords with instant MD5 output in one simple browser tool.

Features

  • MD5 Hash: Enter text and generate a 32-character MD5 hash with live update and case toggle
  • Password Generator: Customize password length and character types (uppercase, lowercase, digits, symbols). Uses crypto.getRandomValues() for secure random generation
  • MD5 Compare: Compare MD5 hashes of two texts to quickly verify content identity
  • Weak Password Detection: Built-in common weak password MD5 hash database with automatic warnings
  • Batch Export: Copy all results as a table or download as CSV

How to Use

MD5 Hash

  1. Enter the text you want to hash in the input box
  2. Click “Generate MD5” (or enable live update)
  3. Click “Copy” to copy the MD5 hash to clipboard

Password Generator

  1. Set password length (8-32) and character types
  2. Click “Generate One” or “Generate 10”
  3. Use “Copy All” or “Download CSV” to export

MD5 Compare

  1. Enter text in both Text A and Text B input boxes
  2. Click “Compare MD5”
  3. View the result: Match or Mismatch

Use Cases

  • Quick MD5 fingerprint generation for any text
  • Generate strong passwords and save their MD5 values for verification
  • Compare two texts for exact content match
  • Check if a password belongs to common weak passwords

Important Notes

  • MD5 has known collision vulnerabilities. Do not use for password storage or security authentication. Use SHA-256 or stronger instead.
  • All computation happens locally in your browser. No data is uploaded.
  • Password generation uses crypto.getRandomValues() for cryptographic randomness.

FAQ

Is it free?

Yes, completely free. No signup, no limits.

Is data uploaded?

No. All computation happens locally in your browser.

Is MD5 secure?

MD5 has known collision vulnerabilities. Do not use for password storage. We recommend SHA-256 for security. This tool is for quick text fingerprinting and content comparison.

What algorithm for password génération?

Uses the browser's native crypto.getRandomValues() CSPRNG for high-entropy unpredictable passwords.

Is this tool better for debugging, learning, or pre-production checks?

All three. Debugging benefits from fast iteration, learning benefits from immediate visual feedback, and pre-production checks benefit from validating formatting, syntax, and edge cases before deployment.

Will my code or data leave the browser?

Most developer tools here default to browser-side processing, which is better for code snippets, configs, and sensitive text. If any feature depends on a remote model or external API, that is explicitly called out on the page.

How is this different from an IDE plugin or command-line tool?

A web tool is usually faster for quick validation, link sharing, and cross-device use. IDE plugins and CLI tools are stronger when you want the capability embedded into a longer engineering workflow.

Do I need to sign up, download, or install anything?

Most Gotokit tools are designed to open directly in the browser without a separate install. If a tool has a quota, browser requirement, or third-party dependency, the page copy will state that clearly.
