      "summary": "Target file is the AWS-LC SHA-512/SHA-384 implementation, including init/update/final routines, state import/export helpers, and CPU-dispatched compression paths. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload indicators and found no concrete supply-chain compromise signals.",

      "summary": "The target file implements the SSHKDF key-derivation routine using EVP digest primitives, with basic input validation, digest chaining, and FIPS service-indicator bookkeeping.

      "summary": "Reviewed this C++ gtest file for SSHKDF behavior. It only exercises argument validation and known-answer tests via local test vectors, and I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain abuse in the target file.",
