Review rev_c2f7e4c4247542338daac276b8eda728

{
  "summary": "Reviewed `aws-lc/util/fipstools/acvp/acvptool/subprocess/ml_kem.go`, which is a straightforward ML-KEM ACVP test-vector dispatcher that unmarshals JSON input and routes keyGen/encapDecap cases to local `Transact` calls. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, hidden payload execution, or persistence in this file.\nReviewed `aws-lc/crypto/x509/algorithm.c`, which implements X.509 signature algorithm encoding and verification dispatch for digest/key OID handling. I checked for install hooks, subprocess execution, network or exfiltration paths, credential access, dynamic code loading, obfuscation, and persistence mechanisms, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/include/openssl/conf.h`, which is a public OpenSSL-compatible configuration API header with declarations for config parsing and deprecated no-op config functions. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file.\nReviewed the ARM64 assembly routine in aws-lc/third_party/s2n-bignum/arm/p521/bignum_tolebytes_p521.S. It is a straight-line conversion of nine 64-bit limbs into 66 little-endian bytes, and I found no concrete malicious or supply-chain indicators such as install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed `aws-lc/crypto/bio/hexdump.c`, which implements a local BIO hexdump formatter by converting bytes into hexadecimal and ASCII output. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/deobfuscation, or persistence mechanisms.",
