      "summary": "Reviewed `aws-lc/crypto/fipsmodule/sshkdf/sshkdf.c`, which implements the SSHKDF derivation routine by hashing the key, exchange hash, type byte, and session ID into output blocks while managing the FIPS service indicator state. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this file.",
