  "summary": "This file implements PEM/X509 parsing and serialization for certificates, CRLs, and private keys. I checked for install-time execution, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in the target file.\nReviewed the PKCS7 BIO cipher wrapper in `aws-lc/crypto/pkcs7/bio/cipher.c`, which implements buffered encrypt/decrypt plumbing and BIO control handling for supported EVP ciphers. I checked for install-time hooks, network or exfiltration paths, credential/secret access, dynamic code loading, obfuscation, persistence tampering, and hidden subprocess execution; none were present.\nThis file is a normal CRL implementation for ASN.1 parsing, extension handling, signature verification, and revoked-certificate lookup. I checked for install-time hooks, network or exfiltration behavior, credential or secret access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators.",
