  "summary": "Reviewed this header-only ECDH API declaration file. It contains public function prototypes, error-code macros, and explanatory comments, and I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in the target file.\nReviewed this ARM assembly routine for selecting the n-th bignum digit. It is a straightforward constant-time indexed load/selection loop and I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain payload behavior in this file.\nReviewed this x86-64 assembly helper, which simply ORs six 64-bit limbs and returns 1 when the bignum is nonzero and 0 otherwise. I checked for install-time hooks, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation/deobfuscation, and persistence or environment tampering, and found none.\nReviewed `aws-lc/crypto/x509/a_verify.c`, which implements ASN.1/X.509 signature verification by initializing an `EVP_MD_CTX`, encoding the input object, and calling `EVP_DigestVerify`. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file.\nReviewed `aws-lc/crypto/x509/x_req.c`, which implements ASN.1 handling for X509 certificate requests and their validation callbacks. I checked for install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.",
