Review rev_761f4571bee1442fb9a18f7e9b0c1a4b

{
  "summary": "Reviewed `aws-lc/crypto/asn1/asn1_par.c`, which is a small ASN.1 tag-to-string helper for OpenSSL-compatible code. I found no concrete malicious or supply-chain indicators: there are no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.\nReviewed `aws-lc/crypto/decrepit/dh/dh_decrepit.c`, which is a small compatibility wrapper that adapts an older Diffie-Hellman parameter-generation callback into `DH_generate_parameters_ex` via `BN_GENCB`. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed `aws-lc/crypto/decrepit/ripemd/ripemd_test.cc`, which is a deterministic unit test for RIPEMD-160 vectors and a million-'a' digest check. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.\nReviewed this RSA compatibility wrapper in `aws-lc/crypto/decrepit/rsa/rsa_decrepit.c`; it only forwards legacy RSA APIs to existing OpenSSL/AWS-LC implementations and contains no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed `aws-lc/crypto/evp_extra/scrypt_test.cc`, which is a GoogleTest unit test for `EVP_PBE_scrypt` covering test vectors, memory-limit handling, and invalid-parameter cases. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise in this target file.",
