{
  "summary": "Reviewed `aws-lc/include/openssl/obj.h`, a public API header for ASN.1 object identifier and NID helpers. It only declares OID/NID lookup, conversion, and registration functions and does not contain install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain indicators.\nReviewed the ARM assembly implementation of `bignum_montmul_sm2_alt`, which performs a fixed-function Montgomery multiplication for SM2 field arithmetic using register-only multiply/add/carry operations and a final conditional subtraction. I checked for install hooks, syscalls, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.\nReviewed this x86-64 assembly routine for P-521 modular multiplication/reduction. It is a straight arithmetic implementation with register shuffling, carry handling, and ABI-specific prologue/epilogue code; I found no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence logic.\nReviewed `aws-lc/crypto/asn1/a_time.c`, which implements ASN.1 time construction, validation, parsing, and conversion helpers for UTCTime and GeneralizedTime. I checked for install hooks, network or exfiltration behavior, credential or secret access, dynamic code loading, obfuscation, persistence, and other hidden payload execution, and found no concrete malicious or supply-chain indicators in this file.\nReviewed this ARM assembly implementation of `bignum_mul_p25519_alt`, which performs fixed-function modular multiplication for Curve25519/P-25519 and writes the result back to the provided output buffer. I checked for install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess behavior, and found no concrete malicious or supply-chain indicators in the target file.",
