{
  "summary": "Reviewed `aws-lc/crypto/x509/rsa_pss.c`, which implements ASN.1 encode/decode and BIO printing for RSA-PSS parameters plus the context conversion helpers used by X.509 signature handling. I checked for install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/crypto/evp_extra/p_dsa.c`, which implements DSA EVP context initialization, parameter generation, signing, verification, and ctrl/ctrl_str dispatch. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network/exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed `aws-lc/crypto/fipsmodule/ml_dsa/mldsa/poly_kl.h`, which is a C header declaring MLDSA polynomial helper APIs and CBMC-style memory/range contracts. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation/deobfuscation pipelines, or persistence/tampering behavior.",
