{
  "summary": "Reviewed this Perl assembly generator for ARM GHASH/NEON code emission. It only parses its two build arguments, optionally pipes output through a local `arm-xlate.pl`, and prints generated assembly; I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading from remote or encoded payloads, obfuscation, or persistence.\nReviewed `aws-lc/crypto/x509/x509_req.c`, which implements X.509 certificate-request helper routines for reading and writing request attributes, extensions, public keys, and signature metadata. I found no concrete malicious or supply-chain indicators: there are no install hooks, network or exfiltration calls, secret/credential access, dynamic code loading, obfuscation, or persistence behavior in this file.\nReviewed this Perl assembly-generator script, which emits bn_mul_comba and bn_sqr_comba x86 routines into the requested output file. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence; the file appears to be a local code generator only.",
