🔒 Overview
API encryption is crucial for securing data in transit. This guide explains key concepts, methods, and best practices for implementing encryption in your API workflows. Always ensure sensitive data is protected using industry-standard protocols.

🔐 Encryption Methods

1. Symmetric Encryption

Uses a single key for both encryption and decryption.

  • Algorithms: AES-256, DES, 3DES
  • Use Case: Ideal for encrypting large data volumes
    Symmetric Encryption

2. Asymmetric Encryption

Relies on a public/private key pair.

  • Algorithms: RSA, ECC
  • Use Case: Secure key exchange over insecure channels
    Asymmetric Encryption

3. Hash Functions

Convert data into a fixed-size string (not reversible).

  • Algorithms: SHA-256, bcrypt
  • Use Case: Password storage and data integrity verification
    Hash Function

🔒 Security Best Practices

  • Always use HTTPS to encrypt communication between client and server
  • Implement TLS 1.3 or higher for robust transport layer security
  • Regularly update encryption algorithms to address vulnerabilities
  • Store cryptographic keys securely (e.g., in a Key Management Service)
  • Use AES-GCM mode for authenticated encryption
