Security Best Practices

  • Use SHA-256 or SHA-512 for modern security
  • Avoid MD5 for sensitive data (deprecated)
  • Consider algorithm speed vs security trade-offs
  • Store hashes, never plain text passwords
  • Use salt values for password hashing

Common Use Cases

  • Password storage and verification
  • File integrity verification
  • Digital signatures and certificates
  • Blockchain and cryptocurrency
  • Data deduplication systems

Understanding Hash Algorithms

Cryptographic hash functions are mathematical algorithms that transform input data of any size into a fixed-size string of characters. These functions are designed to be one-way operations, making it computationally infeasible to reverse the process.

Algorithm Characteristics:

MD5 (Message Digest 5)

128-bit hash function producing 32-character hexadecimal strings. Fast but cryptographically broken due to collision vulnerabilities. Suitable for checksums, not security.

SHA-1 (Secure Hash Algorithm 1)

160-bit hash producing 40-character strings. More secure than MD5 but also deprecated for security purposes due to collision attacks discovered in 2017.

SHA-256

256-bit member of SHA-2 family. Produces 64-character strings. Currently secure and widely used for digital signatures, certificates, and blockchain applications.

SHA-512

512-bit SHA-2 variant producing 128-character strings. Higher security margin than SHA-256 but slower. Ideal for high-security applications and longer-term data protection.
