What is Hash Generator?

A hash generator creates cryptographic hash values from text input using algorithms like SHA-1, SHA-256, SHA-384, and SHA-512. Hash functions transform any input into a fixed-length string of characters that serves as a unique digital fingerprint. Our tool uses the Web Crypto API built into your browser for secure, standards-compliant hash generation. Hashes are commonly used for data integrity verification, password storage, and digital signatures. Since all hashing happens locally in your browser, your sensitive data is never exposed to external servers.

How to Use Hash Generator

  1. Enter or paste the text you want to hash in the input field.
  2. Select your preferred hashing algorithm (SHA-256 is recommended for most uses).
  3. Click 'Generate Hash' to compute the hash value.
  4. Copy the resulting hash string for use in your application or verification process.

Common Use Cases

  • Verifying file integrity by comparing hash checksums after downloads
  • Generating hash values for password storage and authentication systems
  • Creating unique identifiers for data deduplication and caching

FAQ

What is a hash?

A hash is a fixed-length string of characters generated from input data using a mathematical algorithm. The same input always produces the same hash, but it's practically impossible to reverse.

Which algorithm should I use?

SHA-256 is the most commonly used for general purposes. SHA-512 provides extra security. SHA-1 is considered weak and should only be used for non-security checksums.

Is MD5 supported?

The Web Crypto API does not support MD5 natively due to its known vulnerabilities. We provide SHA-1, SHA-256, SHA-384, and SHA-512.

Is my text secure?

Yes. All hashing happens in your browser using the Web Crypto API. Your text is never sent to any server.
