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.
RSA
AES
PBKDF2
Diffie-Hellman
SHA-256
3DES
ECC
MD5
HMAC
DSA
Stronger legacy symmetric encryption than DES
Fast symmetric encryption for bulk data
Robust hashing function for ensuring data integrity
Key stretching with salts for secure password storage
Legacy hashing function prone to collisions
Digital signature creation and verification
Asymmetric encryption with smaller key sizes and high security
Asymmetric encryption suitable for secure key exchange
Secure key exchange without transmitting keys
Keyed hashing mechanism for data authenticity
