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