{
  "summary": "Reviewed `aws-lc/crypto/fipsmodule/bn/sqrt.c`, which implements modular square-root and integer square-root routines using Tonelli-Shanks and Newton iteration. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation/deobfuscation, or persistence behavior.\nReviewed aws-lc/crypto/asn1/a_strex.c, which implements ASN.1 string and time formatting/escaping helpers for BIO output. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/packing, and persistence/tampering, and found no concrete malicious or supply-chain indicators.",
