  "summary": "`aws-lc/ssl/test/runner/sign.go` implements TLS signature algorithm selection plus RSA, ECDSA, PSS, and Ed25519 signing/verification helpers for the test runner. I checked for install-time execution, network/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/bio/file.c`, which implements the file-backed BIO methods for opening, reading, writing, seeking, and closing local `FILE *` streams. I did not find concrete malicious or supply-chain indicators: there are no install hooks, network/exfiltration paths, credential access, hidden downloads, dynamic code loading, obfuscation, or persistence behavior in this file.\nReviewed `aws-lc/crypto/kyber/pqcrystals_kyber_ref_common/indcpa.c`, which is a straightforward Kyber IND-CPA implementation covering key packing/unpacking, rejection sampling, matrix generation, encryption, and decryption. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/deobfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.",
