About Hash Functions

A hash function takes an input (or 'message') and returns a fixed-size string of bytes. The output is typically a 'digest' that is unique to each unique input.

Common hash algorithms:

  • MD5: 128-bit hash value. Fast but considered cryptographically broken.
  • SHA1: 160-bit hash value. More secure than MD5 but also considered insecure.
  • SHA256: 256-bit hash value. Part of the SHA-2 family, widely used and secure.
  • SHA512: 512-bit hash value. Stronger than SHA256 but produces larger hashes.

Common uses of hashing:

  • Data integrity verification
  • Password storage (with salt)
  • Digital signatures
  • Blockchain technology

Security Note: For password storage, always use a slow hashing algorithm like bcrypt, scrypt, or Argon2 with a unique salt for each password.
