Review rev_4d767b5ddbcc4773aa90db953604d119

{
  "summary": "Reviewed `aws-lc/crypto/x509/v3_ocsp.c`, which implements OCSP-related X509 v3 extension handlers and ASN.1 helpers for OCSP nonce and noCheck values. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network/exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence behaviors.\nReviewed this x86-64 assembly routine for `z := (3 * x) mod p_521`, including its register setup, arithmetic, conditional reduction, and ABI save/restore paths. I found no concrete malicious or supply-chain indicators: there are no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence mechanisms in the target file.\nReviewed `aws-lc/include/openssl/des.h`, which is a public DES/3DES API header defining types, constants, and function prototypes plus deprecation guidance. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/deobfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/crypto/crypto.c`, which is a small AWS-LC/OpenSSL compatibility layer for library initialization, version reporting, and cleanup helpers. I found no concrete supply-chain or malicious indicators: the file contains no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, or persistence behavior; the only notable runtime action is a bounded `RAND_bytes` call in `CRYPTO_pre_sandbox_init` to warm up the RNG before sandboxing.\nReviewed `aws-lc/crypto/decrepit/blowfish/blowfish_test.cc`, which is a straightforward Blowfish cipher test suite exercising ECB, CBC, and CFB encryption/decryption against fixed local test vectors. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file.",
