About SHA

SHA (Secure Hash Algorithm) is a family of cryptographic hash functions designed by the NSA

SHA Algorithms
    SHA-1: SHA-1 produces 160-bit hash but is deprecated due to security vulnerabilities
  • SHA-256: SHA-256 produces 256-bit hash and is currently secure for use
  • SHA-512: SHA-512 produces 512-bit hash and provides high security
  • SHA-3: SHA-3 is the latest standard with completely different structure
Security Uses
Common Applications
  • Digital signatures
  • File integrity verification
  • Password hashing
  • Blockchain technology
  • Digital certificates
  • Digital forensics
Security Considerations
  • Do not use SHA-1 for new security applications
  • Always use unique, random salts with passwords
  • Consider key stretching algorithms like bcrypt for passwords
  • Use cryptographically secure random number generators
