Review rev_4dd3eb0ff3e446449ac17b1b865906b8

{
  "summary": "Reviewed `aws-lc/ssl/ssl_decrepit.c`, which implements `SSL_add_dir_cert_subjects_to_stack` by iterating a filesystem directory, building paths, and passing each file to the certificate loader. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.\nReviewed the SHA-3 header in `aws-lc/third_party/jitterentropy/jitterentropy-library/src/jitterentropy-sha3.h`, which only defines hashing context types, size macros, and function prototypes. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed `aws-lc/crypto/decrepit/obj/obj_decrepit.c`, which is a small wrapper that adapts OpenSSL cipher and digest iteration callbacks into `OBJ_NAME` records and dispatches based on `type`. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this file.\nReviewed `aws-lc/crypto/hrss/internal.h`, which only defines HRSS polynomial sizes/types and declares multiplication/inversion APIs plus an optional x86-64 assembly fast path. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence logic.\nReviewed this header as a declaration-only interface for VM UBE/SysGenID detection in AWS-LC. It only exposes exported functions, a default device path constant, and an explicit testing-only helper; I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this file.",
