20+ practice questions focused on Cryptography — one of the most tested topics on the Systems Security Certified Practitioner SSCP exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Cryptography PracticeA security analyst is recommending a symmetric encryption algorithm for a new application that requires both confidentiality and authentication. Which algorithm and mode combination should they select?
Explanation: AES-GCM (Galois/Counter Mode) is a symmetric encryption algorithm that provides both confidentiality and authentication in a single, efficient operation. It combines AES encryption in counter mode with a Galois field-based message authentication code (GMAC), making it ideal for applications requiring both security properties.
An organization is implementing a digital signature solution to ensure non-repudiation of documents. Which combination of keys is used during the signing process?
Explanation: Digital signatures use asymmetric cryptography where the sender creates a signature with their private key, and the recipient verifies it with the sender's public key. This ensures non-repudiation because only the sender possesses their private key, so they cannot deny having signed the document. The process typically involves hashing the document and encrypting the hash with the sender's private key.
A company is deploying a VPN using IPsec. They want to ensure that even if the private key of the server is compromised, past session keys cannot be derived. Which key exchange method should they use?
Explanation: Ephemeral Diffie-Hellman (DHE or ECDHE) provides perfect forward secrecy (PFS) because it generates a unique, temporary session key for each session using ephemeral key pairs. Even if the server's long-term private key is compromised, past session keys cannot be derived because they were created from ephemeral keys that are discarded after each session. This ensures that historical encrypted traffic remains secure.
A security administrator is configuring a web server to use TLS. They want to optimize performance while maintaining strong security. Which cipher suite should they prioritize?
Explanation: Option D is correct because TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384 uses Elliptic Curve Diffie-Hellman Ephemeral (ECDHE) for perfect forward secrecy, ECDSA for efficient authentication, AES-256 in GCM mode for authenticated encryption, and SHA-384 for integrity. This combination provides the strongest security with modern, optimized algorithms, making it the best choice for performance and security on a TLS web server.
Which of the following hash algorithms is considered cryptographically broken and should be avoided due to collision attacks?
Explanation: MD5 is known to have collision vulnerabilities and is no longer considered secure.

Practice all Cryptography questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Cryptography. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Cryptography questions on the SSCP frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Cryptography is tested as part of the Systems Security Certified Practitioner SSCP blueprint. Practicing with targeted Cryptography questions ensures you can handle any format or difficulty that appears.
