  "summary": "Reviewed this header-only ECDSA API declaration file. It contains function prototypes for signing, verifying, ASN.1 marshaling, and one explicitly documented testing-only nonce helper; I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in the target file.\nReviewed this x86-64 assembly implementation of `bignum_madd_n25519_alt`, which performs Curve25519/edwards25519 modular multiply-add and writes the reduced 256-bit result back to the caller. I checked for install hooks, subprocess launches, network or exfiltration, credential access, dynamic code loading, obfuscation/decoding, and persistence tampering, and found no concrete malicious or supply-chain indicators.\nReviewed `aws-lc/crypto/asn1/posix_time.c`, which implements UTC-only conversions between POSIX time and `struct tm` along with range checks and adjustment helpers. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise signals in this file.\nReviewed `aws-lc/crypto/kyber/pqcrystals_kyber_ref_common/polyvec.c`, which is a straightforward Kyber polynomial-vector helper implementing compression/decompression, byte serialization, NTT transforms, base multiplication, reduction, and addition. I found no concrete malicious or supply-chain indicators: there are no install hooks, network/exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.",
