  "summary": "Reviewed aws-lc/ssl/t1_enc.cc, which implements TLS 1.x/1.3 key derivation and exporter logic using local session secrets, transcript hashes, and randoms. I checked for install-time hooks, hidden subprocesses, credential access, network/exfiltration, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/crypto/x509/x_crl.c`, which implements X.509 CRL ASN.1 parsing, cached extension handling, verification, and revoked-entry lookup. I checked for install hooks, hidden subprocesses, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/third_party/s2n-bignum/arm/p521/bignum_montsqr_p521_alt.S`, a straight-line ARM64 Montgomery squaring routine for P-521 that only performs register arithmetic, stack save/restore, and final 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 signals in this target file.",
