Review rev_67760c1b548648759fe85a6f3cc0fda3

{
  "summary": "Reviewed this x86-64 assembly routine that exposes three aliases for copying six 64-bit words into little-endian form. It contains only fixed-load/fixed-store operations and ABI shims, with no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed `aws-lc/crypto/ec_extra/internal.h`, which is a small C/C++ header exposing internal hash-to-curve and hash-to-scalar function declarations for EC groups. I found no concrete supply-chain or malicious indicators in this file: no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.\nReviewed `aws-lc/crypto/engine/engine.c`, which is a small OpenSSL ENGINE shim that only allocates/frees an `ENGINE` struct, stores and վերադարձs RSA/EC method pointers, and defines a no-op cleanup. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this target file.\nReviewed `aws-lc/crypto/x509/x_exten.c`, which only defines ASN.1 structures and helper macros for X509 extensions and extension sequences. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain abuse in this target file.\nReviewed this `CMakeLists.txt` as a build configuration file that adds the `aws-lc` subdirectory, sets output directories, and conditionally adjusts target prefixes and definitions. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence/tampering logic.",
