{
  "summary": "This file is a Perl perlasm generator that emits optimized x86_64 MD5 assembly and, for Win64, SEH metadata. I checked it for install hooks, network/exfiltration, credential access, dynamic code loading beyond the local xlate pipe, obfuscation, persistence, and other hidden payload behavior; no concrete malicious or supply-chain indicators were found.\nReviewed this ARM assembly implementation of `secp256k1_jmixadd_alt`, which performs Jacobian mixed-point addition with modular field arithmetic and a final conditional selection for the point-at-infinity case. I found no concrete malicious or supply-chain indicators in the target file: no install hooks, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, or persistence tampering.\nReviewed `aws-lc/crypto/evp_extra/print.c`, which is a normal EVP key-printing implementation for RSA, DSA, EC, and PQDSA/MLDSA key types. I checked for install hooks, network or exfiltration paths, credential or environment harvesting, dynamic code loading, obfuscation/packing, and persistence, and found no concrete malicious or supply-chain indicators in this file.",
