Hash Generator

Type or paste any text and instantly generate MD5, SHA-1, SHA-256, and SHA-512 hashes. All hashing is performed locally in your browser using the Web Crypto API.

Salt is prepended to your input before hashing. Adding a salt makes identical inputs produce unique hashes.

How to Use the Hash Generator

  1. Type or paste your input text into the text area.
  2. Hashes for MD5, SHA-1, SHA-256, and SHA-512 are generated automatically as you type.
  3. Click the Copy button next to any hash algorithm to copy that hash value.
  4. Toggle Uppercase to display hashes in uppercase hex if needed.
  5. All processing happens entirely in your browser — your input is never sent to a server.

Note: MD5 and SHA-1 are provided for legacy compatibility checks only and are not considered cryptographically secure.

About This Tool

This hash generator works as an MD5 generator, SHA-256 hash calculator, SHA-512 hash tool, text checksum generator, and cryptographic hash function tester. Enter any string or paste text to instantly see all five hash outputs simultaneously.

Useful for verifying file integrity, comparing checksums, testing password hashing behavior, debugging authentication logic, or learning how hash functions transform input. All hashing uses your browser’s native SubtleCrypto API — your data never leaves your device.
