What are Hashes?

A hash function converts input data into a fixed-size string of characters, which appears random but is deterministic.

Key properties:

  • Same input always produces same hash
  • Small input change completely changes hash
  • Practically impossible to reverse
  • Fast to compute

Common Use Cases

  • Password storage (with salt)
  • File integrity verification
  • Digital signatures
  • Blockchain and cryptocurrency
  • Data deduplication
  • Checksum generation
Note: MD5 and SHA-1 are cryptographically broken. Use SHA-256 or SHA-512 for security-critical applications.
