{
  "summary": "Reviewed `aws-lc/crypto/x509/x509_set.c`, which contains standard X.509 certificate field setters/getters and signature-info helpers. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise in this file.\nReviewed the X509 time unit test in `aws-lc/crypto/x509/x509_time_test.cc`. It only constructs ASN.1 time values and checks comparison behavior; I found no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain indicators in this file.\nReviewed the target assembly implementation of `bignum_mul_p521_alt`, which performs constant-time modular multiplication for P-521 using x86-64 arithmetic and stack/register management. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence tampering, or hidden subprocess execution.",
