AES Encryption

Symmetric

How it works: AES uses the same key for both encryption and decryption. It's incredibly fast and secure for bulk data encryption.

Key Size: 256 bits
Mode: CBC
Speed: Very Fast

Pros:

  • Extremely fast encryption/decryption
  • Secure for large amounts of data
  • Widely adopted and tested
  • Hardware acceleration available

Cons:

  • Key distribution challenge
  • Same key for encrypt/decrypt
  • No built-in authentication

RSA Encryption

Asymmetric

How it works: RSA uses different keys for encryption and decryption. It's perfect for secure key exchange and digital signatures.

Key Size: 2048-4096 bits
Padding: OAEP
Moderate

Pros:

  • Solves key distribution problem
  • Enables digital signatures
  • Mathematically proven security
  • Perfect for key exchange

Cons:

  • Much slower than AES
  • Limited data size per operation
  • Larger key sizes needed

Security Best Practices

Key Management

Always use secure random key generation and store keys safely. Never hardcode encryption keys in your applications.

Algorithm Selection

Use AES for bulk data encryption and RSA for key exchange and digital signatures. Consider hybrid systems for optimal security and performance.

Regular Updates

Keep cryptographic libraries updated and monitor for security advisories. Cryptography evolves constantly.

Defense in Depth

Encryption is just one layer. Implement proper access controls, secure key storage, and regular security audits.
