{
  "summary": "Reviewed `aws-lc/crypto/fipsmodule/modes/gcm_nohw.c`, a constant-time GHASH/POLYVAL implementation used for AES-GCM fallback paths. I found no concrete supply-chain or malicious indicators in this file: there are no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed `aws-lc/crypto/evp_extra/p_dsa_asn1.c`, which implements DSA public/private ASN.1 encode/decode and EVP_PKEY method wiring. I checked for install hooks, subprocess execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/include/openssl/sha.h`, which is a declarative OpenSSL-compatible SHA family header exposing hash constants, state structs, and function prototypes for SHA-1/2 variants. I found no concrete malicious or supply-chain indicators: there are no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, persistence, or other payload-execution behavior in this file.",
