About File Hashing

What are Hash Functions?

Hash functions generate a fixed-size string (hash) from input data. The same input always produces the same hash, making them useful for verifying file integrity and detecting changes.

Common Uses:
  • • File integrity verification
  • • Download verification
  • • Digital signatures
  • • Password storage
  • • Data deduplication
Algorithm Comparison:
  • • MD5: Fast but cryptographically broken
  • • SHA-1: Deprecated for security use
  • • SHA-256: Current standard, secure
  • • SHA-512: Longer hash, more secure
  • • SHA-3: Latest SHA standard
  • • RIPEMD160: Alternative to SHA-1
