  "summary": "Reviewed `aws-lc/crypto/decrepit/cast/cast_test.cc`, which is a straightforward GoogleTest fixture validating CAST5 ECB/CBC encryption and decryption against fixed test vectors. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden execution paths, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/crypto/dilithium/p_dilithium3.c`, which is a straightforward EVP method binding for Dilithium3 key generation, signing, and verification. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/ssl/CMakeLists.txt`, which only declares the `ssl` library, links it to `crypto`, sets include paths, defines test executables under `BUILD_TESTING`, and installs/exported CMake metadata. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this target file.\nReviewed the target assembly routine `bignum_add_p521`, which implements a constant-size modular addition for P-521 with ABI shims and register save/restore. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this file.\nThe target file is a small C source implementing DH `EVP_PKEY` ASN.1/method glue and key accessor helpers. I checked it for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence tampering, and other hidden execution paths, and found no concrete malicious or supply-chain indicators.",
