Cryptographic Concepts
CompTIA Security+ SY0-701 (V7) PBQ
Match cryptographic algorithms and methods with their appropriate applications and security strengths. This exercise reinforces understanding of when to apply different encryption types, hashing functions, and digital signature methods.
HMAC
AES
SHA-256
PBKDF2
RSA
MD5
3DES
DSA
ECC
Diffie-Hellman
Stronger legacy symmetric encryption than DES
Keyed hashing mechanism for data authenticity
Fast symmetric encryption for bulk data
Legacy hashing function prone to collisions
Asymmetric encryption with smaller key sizes and high security
Robust hashing function for ensuring data integrity
Asymmetric encryption suitable for secure key exchange
Digital signature creation and verification
Key stretching with salts for secure password storage
Secure key exchange without transmitting keys
