Hash Algorithm Information

General Purpose Hashing

  • SHA-256: Best for digital signatures, SSL, file integrity
  • SHA-512: Higher security variant of SHA-2
  • SHA3-256/512: Modern alternative to SHA-2

Deprecated Algorithms

  • MD5: Use only for non-security checksums
  • SHA-1: Being phased out, avoid for new applications

Password Hashing

  • Argon2: Winner of Password Hashing Competition 2015
  • bcrypt: Industry standard for password storage

Security Best Practices

  • Never use MD5 or SHA-1 for security
  • Always use bcrypt or Argon2 for passwords
  • Add salt to hashes when possible
  • Use SHA-256 or higher for file integrity

Common Use Cases

File Integrity Verification

Use SHA-256 or SHA-512 to verify downloaded files haven't been tampered with

Password Storage

Use Argon2 or bcrypt with automatic salt generation for secure password storage

Digital Signatures

Use SHA-256 or SHA-512 for signing documents and verifying authenticity

Blockchain & Cryptocurrencies

SHA-256 is widely used in Bitcoin and other blockchain technologies
