  "summary": "Reviewed this ARM64 assembly implementation of P-384 Montgomery multiplication. It is a fixed arithmetic routine with register save/restore and result correction logic; I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other payload-delivery mechanisms.\nReviewed `aws-lc/crypto/bn_extra/convert.c`, which implements BIGNUM string and MPI/byte conversion helpers (`BN_bn2hex`, `BN_hex2bn`, `BN_bn2dec`, `BN_asc2bn`, `BN_print`, `BN_bn2mpi`, `BN_mpi2bn`, `BN_bn2binpad`). I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation/decoding payloads, or persistence behavior in this target file.",
