{
  "summary": "Reviewed `aws-lc/crypto/asn1/f_int.c`, which only formats `ASN1_INTEGER`/`ASN1_ENUMERATED` values into hexadecimal text via `BIO_write`, with line-wrapping for long outputs. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise in this file.\nReviewed the target C source implementing Kyber/ML-KEM SHAKE-based absorb, squeeze, PRF, and rkprf helpers. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.\nReviewed `aws-lc/crypto/asn1/a_dup.c`, which only implements in-memory ASN.1 duplication helpers by encoding and decoding via OpenSSL `i2d`/`d2i` routines and freeing the temporary buffer. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this file.\n`aws-lc/crypto/fipsmodule/ec/felem.c` is a small elliptic-curve field-element helper module that converts between `BIGNUM` and field representations and provides constant-time arithmetic/comparison helpers. I checked it for install-time hooks, network or exfiltration behavior, 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/evp_errors.h`, which is a small OpenSSL error-code header defining `EVP_R_*` constants only. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this file.",
