Review rev_8c732181bb9a4182963ca8a9a166cff0

{
  "summary": "Reviewed `aws-lc/crypto/rsa_extra/internal.h`, which is a C/C++ header defining RSA-PSS parameter structs, allocation/free helpers, parsing/creation accessors, and an OAEP padding-check prototype. I found no concrete indicators of install-time execution, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this target file.\nReviewed this x86-64 assembly source for the 384-bit big-endian/bignum byte-reversal helper. It contains only direct register/memory moves and `bswapq` operations with ABI shims for Windows, and I found no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence mechanisms.\nReviewed `src/lib.rs`, which is a thin Rust FFI/bindings entrypoint for aws-lc-fips-sys: it conditionally re-exports generated bindings, provides a few small helper functions, and calls `CRYPTO_library_init()` in `init()`. I found no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this file.\nReviewed `aws-lc/crypto/asn1/a_bool.c`, which only implements ASN.1 boolean encode/decode helpers using in-process OpenSSL/AWS-LC byte-string primitives. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other hidden supply-chain behavior in this file.\nReviewed `aws-lc/crypto/decrepit/cast/internal.h`, which is a plain C header defining CAST cipher constants, key state, S-box declarations, and encryption/decryption function prototypes. I checked for install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, persistence, or other hidden payload behavior and found no concrete malicious or supply-chain indicators in this file.",
