  "summary": "Reviewed the target header as a platform-specific entropy and utility shim for jitterentropy/aws-lc integration. I checked for install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/crypto/decrepit/cast/cast.c`, which is a normal CAST5 block-cipher implementation with ECB/CBC routines and key schedule setup. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden control-flow or payload execution, and found no concrete malicious or supply-chain indicators.",
