Review rev_7742bb2efd1f4ac79239706d5040d644

{
  "summary": "Reviewed `aws-lc/crypto/rand_extra/ccrandomgeneratebytes.c`, which is a small platform-specific randomness wrapper that calls `CCRandomGenerateBytes` on iOS/macOS and aborts on failure. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this file.\nReviewed `aws-lc/crypto/x509/x509_def.c`, which only defines default X.509 certificate path constants and trivial accessor functions returning those hardcoded strings. I checked for install-time execution, network or exfiltration paths, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.\nReviewed this linker script, which only defines `.text` and `.rodata` output sections for the FIPS module and discards a few unexpected relocation/data sections. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.\nReviewed this internal header, which only declares `HMAC_with_precompute` for FIPS ACVP harness use and contains no implementation logic. I checked for install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence tampering, or other hidden payload indicators and found none.\nReviewed `aws-lc/include/openssl/type_check.h`, a small C/C++ header that defines two compile-time checked cast macros and no runtime logic. I checked for install-time hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution, and found no concrete malicious or supply-chain indicators.",
