Review rev_32305b40af8e4d5baa349365edc68ace

{
  "summary": "Reviewed this x86-64 assembly implementation of `bignum_shl_small`, which performs an in-memory left shift of big integers and ABI-specific register shuffling. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise signals in the target file.\nReviewed the AArch64 assembly routine `mlkem_poly_mulcache_compute_asm`, which is an auto-derived polynomial cache computation function for ML-KEM. I checked the target file for install-time hooks, network or exfiltration, credential access, dynamic code loading, obfuscation/deobfuscation, persistence, and other hidden execution paths, and found no concrete malicious or supply-chain indicators.\nReviewed `aws-lc/crypto/pkcs7/internal.h`, which is a C header declaring PKCS#7-related ASN.1 structures and helper APIs for parsing, encoding, and cipher BIO handling. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation/deobfuscation, persistence, or hidden subprocess behavior.\nReviewed `SSL_SESSION_print` in `aws-lc/ssl/ssl_text.cc`, which is a straightforward diagnostic printer for SSL session state and writes fields like cipher, session IDs, ticket, and secrets to a caller-supplied BIO. I checked for install hooks, network/exfiltration, credential harvesting, 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 implementing `bignum_triple_p256k1_alt`, which multiplies a 256-bit value by 3 and conditionally reduces it modulo `p_256k1`. 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 in this file.",
