  "summary": "Reviewed aws-lc/crypto/cipher_extra/e_rc2.c, which implements RC2 key scheduling and CBC encrypt/decrypt routines for the EVP cipher interface. I found no concrete indicators of supply-chain compromise or malicious behavior in this file: no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence logic.\nReviewed `aws-lc/crypto/x509/v3_conf.c`, which implements X.509 extension parsing and construction from OpenSSL-style config values, including generic ASN.1 and hex-encoded extension handling. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic remote code loading, obfuscation, persistence, or other supply-chain compromise in this file.",
