Hash Calculator

Calculate MD5, SHA1, SHA256 and other hash values for files or text, used for file verification and security validation

Common Uses

File Integrity Verification

Verify downloaded files are complete and unmodified

Password Security Storage

Convert passwords to hash values for secure storage

Data Consistency Check

Ensure data hasn't been modified during transmission

Algorithm Information

  • MD5: Fast but less secure, suitable for non-security checksums
  • SHA-1: More secure than MD5, but no longer recommended for security applications
  • SHA-256: Currently widely used secure hash algorithm, recommended
  • SHA-512: Higher security hash algorithm, suitable for high-security requirements
  • Uses: File verification, password storage, digital signatures, blockchain, etc.
  • All calculations are performed in the browser, protecting file and data privacy
