  "summary": "Reviewed `aws-lc/crypto/asn1/a_int.c`, which implements ASN.1 INTEGER/ENUMERATED encode-decode helpers, BIGNUM conversions, and integer range/representation checks. I found no concrete malicious or supply-chain indicators in this file: no install-time hooks, subprocess execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/packing, or persistence/tampering logic.\nReviewed `aws-lc/crypto/fipsmodule/ecdsa/ecdsa.c`, which is a standard ECDSA sign/verify implementation plus a small testing helper. I checked for install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence/tampering behavior, and found no concrete malicious or supply-chain indicators in this file.",
