Hash Generator (MD5, SHA) Online — Free Tool

Compute cryptographic hashes including MD5, SHA-1, SHA-256, SHA-384, and SHA-512 securely in your browser.

About this tool

Cryptographic hash functions map input of any size to a fixed-length digest. The same input always produces the same hash, but tiny input changes produce completely different outputs—useful for checksums and integrity checks.

Enter text and select an algorithm such as SHA-256 to compute a digest locally. This tool is for verification and learning; do not use it alone for password storage—use dedicated password hashing algorithms in production systems.

Common use cases

  • Verifying file or string integrity with a known digest
  • Generating test vectors for security coursework
  • Comparing hash outputs across environments

How to use

  1. Configure the tool using the controls above.
  2. Generate or transform your content.
  3. Copy or download the result.
