What are Cryptographic Hashes?

A cryptographic hash function takes input data and produces a fixed-size string of bytes. The same input always produces the same hash, but even a tiny change in input creates a completely different hash.

Hash Algorithms

  • SHA-256: 256-bit hash, widely used for security
  • SHA-384: 384-bit hash, higher security
  • SHA-512: 512-bit hash, maximum security

Common Uses

  • Password verification (with salting)
  • File integrity checking
  • Digital signatures
  • Blockchain and cryptocurrencies
  • Data deduplication
