Final answer:
The NSRL primarily uses the SHA-256 algorithm, not SHA-1, as its hashing algorithm because SHA-256 is more secure against collision attacks.
Step-by-step explanation:
The statement that the NSRL (National Software Reference Library) primarily uses SHA-1 as the hashing algorithm is false. NSRL has moved to using the SHA-256 algorithm for hashing due to the well-documented vulnerabilities and weaknesses found in SHA-1. It is critical for a reference library, which provides a repository of known software, file profiles, and file signatures for use in legal and forensic applications, to utilize secure and reliable hashing algorithms. The move from SHA-1 to SHA-256 improves the robustness against collision attacks, where two different inputs produce the same hash output, which is a significant security concern.
