  "summary": "Reviewed `aws-lc/crypto/asn1/a_strex.c`, which implements ASN.1 string and time rendering/escaping via local BIO writes, hex dumping, and UTF-8/ASN.1 conversions. I found no concrete malicious or supply-chain indicators: no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation/deobfuscation, persistence, or hidden subprocess execution.\nReviewed `aws-lc/crypto/fipsmodule/ec/ec_montgomery.c`, which implements Montgomery-field elliptic-curve point and field arithmetic for AWS-LC/FIPS. I checked for install hooks, network or exfiltration code, credential/secret access, dynamic code loading, obfuscation/decoding pipelines, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.",
