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.
DSA
SHA-256
3DES
Diffie-Hellman
MD5
HMAC
PBKDF2
RSA
ECC
AES
Secure key exchange without transmitting keys
Robust hashing function for ensuring data integrity
Key stretching with salts for secure password storage
