Review rev_484ee054ec6b4a96a4a85dd4f6998824

{
  "summary": "Reviewed `include/rust_wrapper.h`, which is a C header that only pulls in AWS-LC/OpenSSL declarations, defines export/prefix macros, and exposes three `ERR_GET_*_RUST` wrapper prototypes for Rust bindings. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this target file.\nReviewed aws-lc/crypto/fipsmodule/ml_kem/mlkem/sampling.h, which only declares ML-KEM polynomial sampling APIs, macros, and FIPS contracts for centered-binomial and rejection-sampling routines. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this target file.\nReviewed `aws-lc/crypto/x509/v3_skey.c`, which implements subject-key-identifier ASN.1 encoding/decoding and SHA-1 derivation from a public key. I checked for install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other payload-execution behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed the ARM assembly implementation of `bignum_cmadd`, which performs a bounded multiply-add over big-integer limbs and returns the carry word. I checked the file for install-time hooks, network or exfiltration behavior, secret access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators, and found no concrete malicious behavior or hidden execution paths.\nReviewed this ARM assembly implementation of `bignum_mul`, which performs limb-wise big integer multiplication using register arithmetic and memory loads/stores only. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators, and found no concrete malicious behavior in this file.",
