Cryptographic Integration

Key Concepts in Cryptographic Integration

Cryptographic integration revolves around the use of mathematical algorithms and protocols to secure data. At its core, it involves encryption (transforming data into unreadable formats), decryption (reverting encrypted data to its original form), and hashing (creating fixed-length representations of data). Key concepts include:

• Symmetric Encryption: Uses the same key for encryption and decryption. Examples include AES (Advanced Encryption Standard).
• Asymmetric Encryption: Utilizes a pair of keys—public and private—for encryption and decryption. RSA and ECC (Elliptic Curve Cryptography) are popular examples.
• Digital Signatures: Ensures data authenticity and integrity by verifying the sender's identity.
• Key Management: The process of securely generating, storing, and distributing cryptographic keys.
• Cryptographic Protocols: Frameworks like SSL/TLS and IPsec that enable secure communication over networks.
