Review rev_926ee53fdf794725aa33b2fc77ed116e

{
  "summary": "Reviewed `aws-lc/crypto/fipsmodule/md5/internal.h`, which only contains MD5 internal declarations, constants, and an optional assembly function prototype. I found no concrete malicious or supply-chain indicators in this target file: no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed this header-only API declaration file for SysGenID-based snapshot detection helpers and a testing-only initializer. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in the target file.\nReviewed `aws-lc/crypto/thread_none.c`, which provides the non-threaded fallback implementations for mutex, once, and thread-local helpers. I checked for install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.\nReviewed the `aws-lc/include/openssl/blake2.h` public header, which only declares BLAKE2b-256 hashing types and functions and contains no implementation logic. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise indicators and found none in this file.\nReviewed the x86-64 assembly implementation of `bignum_nonzero_6`, which simply OR-reduces six 64-bit limbs and returns 1 or 0 using ABI-specific register handling. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.",
