What is a Hash Calculator?

A hash calculator computes cryptographic hash values for text input. Hash functions convert data of any size into a fixed-size string of characters, commonly used for data integrity verification, password storage, and digital signatures.

Supported Algorithms

  • MD5: 128-bit hash, fast but not secure for cryptographic purposes
  • SHA-1: 160-bit hash, deprecated for security applications
  • SHA-256: 256-bit hash, part of SHA-2 family, widely used
  • SHA-384: 384-bit hash, higher security
  • SHA-512: 512-bit hash, maximum security

Use Cases

  • Data Integrity: Verify file downloads haven't been tampered with
  • Password Storage: Store password hashes instead of plain text
  • Digital Signatures: Ensure document authenticity
  • Checksums: Compare data for equality without comparing entire content
