{
  "summary": "I reviewed `aws-lc/crypto/asn1/asn1_lib.c`, which implements ASN.1 object parsing/encoding and ASN.1 string helpers. I found no concrete malicious or supply-chain indicators: there are no install hooks, network or exfiltration code, credential access, dynamic loading of remote or encoded payloads, obfuscation, or persistence behavior in this file.\nReviewed `aws-lc/crypto/decrepit/cast/cast_tables.c`, which contains only static CAST cipher S-box lookup tables and related includes. I checked for install hooks, subprocess execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this target file.\nReviewed `aws-lc/include/openssl/digest.h`, which is a public C/C++ header defining digest APIs, context structures, constants, and deprecated compatibility no-ops. I checked it for install-time execution, hidden subprocesses, credential access, network/exfiltration, dynamic code loading, obfuscation, and persistence hooks, and found no concrete malicious or supply-chain indicators in this file.",
