Free, browser-based utilities for everyday developer workflows

Hash Generator (MD5, SHA-1, SHA-256, SHA-512)

Generate hashes for strings using common algorithms. All hashing is done locally in your browser using JavaScript and the Web Crypto API (for SHA-family). This tool is intended for debugging and utilities, not for storing or transmitting sensitive secrets.

Use cases

  • Generate MD5, SHA-1, SHA-256, SHA-512 hashes.
  • Verify checksums by comparing outputs.
  • Useful for file integrity and signatures.

Input text

Paste any text you want to hash. For example, API payloads, identifiers, or sample data. The text is treated as UTF-8 before hashing.

Algorithms:
Output format:
MD5
SHA-1
SHA-256
SHA-512

Note: MD5 and SHA-1 are considered cryptographically weak and should not be used for new security-sensitive designs. They are included here for compatibility and debugging only.

How to use Hash Generator

Type or paste your input text into the field and select the hash algorithm — MD5, SHA-1, SHA-256, or SHA-512. The digest is computed instantly in your browser and can be copied to the clipboard.

Common use cases

Developers use this to verify file integrity checksums and compare them against published hashes. Security engineers use it to hash passwords or tokens for quick comparisons during audits, and QA teams use it to generate deterministic test fixtures from known inputs.

Why run this in your browser?

All processing happens locally in your browser. Your data never leaves your machine, making it safe for sensitive payloads, internal API responses, and confidential configurations.
