      "summary": "Reviewed `aws-lc/crypto/asn1/a_d2i_fp.c`, which is a small wrapper that reads ASN.1 data from a `BIO` or `FILE`, parses it with `ASN1_item_d2i`, and frees the temporary buffer. I checked for install-time hooks, subprocesses, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.",
