  "summary": "Reviewed `aws-lc/crypto/x509/x_all.c`, which contains OpenSSL-compatible X.509/PKCS8/DSA/RSA/EC sign, verify, encode, decode, and digest wrappers built on local ASN.1/BIO helpers. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this target file.\nThis Perl file is an x86 assembler macro/helper library for generating assembly output across ELF, macOS, Windows, and Android targets. I checked it for install-time execution, subprocess spawning, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators.\nReviewed the ppc64le Altivec-optimized SHA-1 block transform in aws-lc/crypto/fipsmodule/sha/sha1-altivec.c. It contains only arithmetic/vector hash scheduling and state update logic; I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence tampering.",
