{
  "summary": "Reviewed `aws-lc/ssl/dtls_record.cc`, which implements DTLS record parsing, replay-window tracking, decryption, and sealing for the TLS stack. I found no concrete indicators of malicious or supply-chain behavior in this file: there are no install hooks, network/exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence mechanisms.\nReviewed the Perl perlasm generator for GHASH SSSE3 assembly, including its local pipe to `x86_64-xlate.pl` and the emitted `gcm_gmult_ssse3` / `gcm_ghash_ssse3` routines. No concrete malicious or supply-chain indicators were found: there were no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.\nReviewed `aws-lc/crypto/fipsmodule/evp/digestsign.c`, which implements EVP digest-sign and digest-verify flows for prehashed signatures, HMAC, and non-prehash algorithms such as Ed25519/Dilithium. I checked for install hooks, hidden subprocess execution, network or exfiltration paths, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.",
