{
  "summary": "Reviewed `aws-lc/crypto/x509/t_crl.c`, which is a CRL pretty-printing helper for X.509 objects. I checked for install hooks, subprocess execution, network or exfiltration paths, credential or environment access, dynamic code loading, obfuscation/deobfuscation, and persistence tampering; none were present in this file.\nReviewed the ARM64 assembly routine in `aws-lc/third_party/s2n-bignum/arm/p384/bignum_deamont_p384.S`, which performs fixed Montgomery reduction and conditional subtraction for P-384 using only local register arithmetic and loads/stores. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise patterns in this target file.\nReviewed the x86-64 assembly implementation of `bignum_triple_p384`, which performs a constant-time modular triple of a 384-bit value and saves/restores the expected callee-saved register(s). 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/evp_extra/p_kem_asn1.c`, which implements KEM EVP_PKEY ASN.1 method helpers for raw key access, parameter/public-key comparison, and cleanup. I found no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this target file.\nReviewed `aws-lc/crypto/lhash/lhash_test.cc`, a GoogleTest unit test for the lhash container that generates short random strings and exercises insert, retrieve, delete, and doall behavior against a mirrored in-memory map. I found no concrete indicators of install-time execution, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain-motivated malicious behavior in this target file.",
