Review rev_3024c0aca1504ba4a69c5e470a8cd2d8

{
  "summary": "Reviewed `aws-lc/include/openssl/sshkdf.h`, which is a public C header declaring SSH KDF constants and the `SSHKDF` API. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this file.\nReviewed `aws-lc/crypto/decrepit/rsa/rsa_decrepit.c`, which is a small RSA compatibility wrapper that forwards deprecated RSA PSS/OAEP helpers to the current `*_mgf1` implementations and allocates/frees RSA/BIGNUM objects. 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 `aws-lc/crypto/des/des_test.cc`, which is a small gtest file exercising DES weak-key and parity behavior. I checked for install-time hooks, network or exfiltration calls, credential access, dynamic code loading, obfuscation/packing, persistence, or other hidden execution and found no concrete malicious or supply-chain indicators.\nReviewed this ARM assembly routine for converting a single 64-bit word into a bignum by storing `n` and zero-filling the remaining limbs. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this file.\nReviewed the OpenBSD AArch64 CPU-capability probe in `aws-lc/crypto/fipsmodule/cpucap/cpu_aarch64_openbsd.c`. It only queries `sysctl(CTL_MACHDEP, CPU_ID_AA64ISAR0)` and sets local capability flags for AES, PMULL, SHA1, SHA256, and SHA512; I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence.",
