  "summary": "Reviewed `aws-lc/crypto/rsa_extra/rsa_crypt.c`, which implements RSA PKCS#1 OAEP and v1.5 padding add/check routines plus RSA public/private encrypt/decrypt wrappers. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution; none were present in this target file.\nReviewed `aws-lc/crypto/fipsmodule/evp/evp_ctx_test.cc`, a gtest unit file that exercises EVP_PKEY_CTX control-string behavior for RSA, EC, DH, HKDF, HMAC, and DSA. I checked for install-time hooks, network or exfiltration, credential/secret access, dynamic code loading, obfuscation/packing, persistence, and other hidden payload execution paths, and found no concrete malicious or supply-chain indicators in this file.",
