NEW QUESTION # 57
(Which attack maps hashed values to their original input data?)
Answer: B
Explanation:
A rainbow table attack uses large, precomputed tables that link hash outputs back to likely original inputs (typically passwords). Instead of storing every password#hash pair directly (which would be huge), rainbow tables store chains created by alternating hash operations with reduction functions, allowing attackers to reconstruct candidate plaintexts that produce a given hash. This makes cracking fast,ifthe target hashes are unsalted and use a known, fast hash function. Salt defeats rainbow tables because the attacker would need separate tables for each salt value, which becomes infeasible when salts are unique and sufficiently large. A dictionary attack is related but typically computes hashes on the fly from a wordlist rather than using precomputed chain structures. A birthday attack targets collisions, not mapping to original data. Brute-force tries all candidates without precomputation.
Because the question explicitly describes mapping hashed values back to original data via a precomputed approach, the correct choice is Rainbow table.
NEW QUESTION # 58
(An organization wants to digitally sign its software to guarantee the integrity of its source code. Which key should the customer use to decrypt the digest of the source code?)
Answer: A
Explanation:
When software is digitally signed, the organization computes a cryptographic hash (digest) of the software (or its manifest) and then signs that digest using the organization's private key. Verification works in the opposite direction: the customer (verifier) uses the organization's public key to validate the signature and recover/confirm the signed digest, then independently hashes the received software and compares the result. If the digests match and the signature validates under the public key, the customer has strong assurance that the software has not been altered since it was signed and that it was signed by the holder of the corresponding private key. The customer never needs the organization's private key-sharing it would destroy security and enable forgery. Likewise, the customer's own keys are irrelevant to verifying the publisher's signature. The organization's public key is typically delivered inside a certificate chain (code signing certificate) so the verifier can also validate publisher identity and trust. Therefore, the customer uses the organization's public key for signature verification (often described as "decrypting" the signed digest).
NEW QUESTION # 59
(What type of encryption uses different keys to encrypt and decrypt the message?)
Answer: B
Explanation:
Asymmetric encryption (also called public key cryptography) uses a pair of mathematically related keys: a public key and a private key. One key is used to encrypt, and the other is used to decrypt, which is the defining "different keys" property asked in the question. In the common confidentiality use case, a sender encrypts a message using the recipient's public key, and only the recipient can decrypt it using their private key. This solves the key distribution problem inherent in symmetric encryption, where both parties must securely share the same secret key in advance. Asymmetric systems also enable digital signatures: the private key signs (creates a signature) and the public key verifies it, providing authenticity and integrity. Symmetric encryption, by contrast, uses the same shared key for both encryption and decryption (even though internal round keys may exist, it is still one shared secret).
"Private key" alone is not a full encryption type, and "secure" is a generic description rather than a cryptographic category. Therefore, the correct answer is D. Asymmetric.
NEW QUESTION # 60
(How can auditing enhance an organization ' s cryptographic practices?)
Answer: D
NEW QUESTION # 61
(Why is it important for cryptography frameworks to adapt over time?)
Answer: C
Explanation:
Cryptography must evolve because threats, computing capabilities, and attack techniques continuously change. Algorithms once considered safe can become vulnerable due to cryptanalysis, implementation attacks, protocol flaws, or sheer increases in available compute power. Examples include the deprecation of SHA-1 for signatures, weakening of RC4, and migration away from older TLS versions and weak cipher suites. Frameworks also need to adapt to new environments-cloud architectures, IoT deployments, mobile devices-and new adversary models, including the long-term risk posed by quantum computing to current public-key systems. Adaptation includes updating standards, increasing key sizes where needed, adopting modern primitives (AEAD modes, stronger KDFs), improving key management practices (rotation, hardware- backed storage), and refining operational guidance (certificate lifetimes, revocation strategies). A rigid structure that never changes would lock organizations into obsolete protections and accumulate risk.
Standardizing obsolete techniques or complying with outdated standards is the opposite of sound security engineering. Therefore, cryptography frameworks must adapt over time to respond to emerging threats and vulnerabilities and to maintain effective protection as the landscape evolves.
