About Hash Functions

Hash functions are mathematical algorithms that convert input data of any size into a fixed-size string of characters. They are commonly used for:

Common Uses:

  • Data integrity verification
  • Password storage (with salt)
  • Digital signatures
  • Blockchain and cryptocurrency
  • File fingerprinting

Security Considerations:

  • MD5 and SHA-1 are deprecated for security
  • SHA-256 and SHA-512 are currently secure
  • Hash functions are one-way (irreversible)
  • Same input always produces same output
  • Small changes create completely different hashes
