Hash Generator (MD5 / SHA)

Generate MD5, SHA-1, SHA-256 or SHA-512 hashes instantly for text. Useful for validating data integrity or generating secure fingerprints.

What Is a Cryptographic Hash?

A cryptographic hash is a one-way mathematical function that transforms input data into a fixed-length string. Hashes are commonly used for data validation, password storage, digital signatures, and integrity verification.

Common Hash Algorithms

  • MD5 — fast but not secure (avoid for security)
  • SHA-1 — deprecated for security-critical apps
  • SHA-256 — industry standard for secure hashing
  • SHA-512 — stronger SHA-2 variant for high-security applications

Example Use-Cases

  • Verifying file integrity
  • Generating unique fingerprints
  • Token signatures
  • Password hashing (with salt — not plain hash)
