Review rev_673228ef621e46f2bb011464eedf487a

{
  "summary": "Reviewed `aws-lc/crypto/fipsmodule/curve25519/internal.h`, which is a C header declaring Curve25519/Ed25519 types and internal crypto routines. I found no concrete supply-chain or malicious indicators in this file: there are no install hooks, subprocess launches, network or exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence/tampering behavior.\nReviewed `aws-lc/include/openssl/curve25519.h`, which is a public C header exposing Curve25519, Ed25519, and SPAKE2 API declarations and constants only. I checked for install-time hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed the target x86-64 assembly routine `bignum_cmul_p521_alt`, which performs a straight-line modular multiplication for the P-521 field and includes only ABI register saving/restoring plus arithmetic reduction logic. I found no concrete malicious or supply-chain indicators in the target file: no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed the Go ECDSA ACVP handler in `aws-lc/util/fipstools/acvp/acvptool/subprocess/ecdsa.go`. It only parses JSON test vectors and dispatches local `keyGen`, `keyVer`, `sigGen`, and `sigVer` calls through the provided `Transactable`; I found no concrete indicators of install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file.\nReviewed `aws-lc/util/godeps.go`, a build-ignored Go utility that walks package imports and emits CMake or depfile dependency lists. I checked for install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other hidden execution paths, and found no concrete malicious or supply-chain indicators in this file.",
