AWS prescriptive-guidance documentation change

Service: prescriptive-guidance · 2026-01-25 · Documentation low

File: prescriptive-guidance/latest/encryption-best-practices/aws-cryptography-services.md

Summary

Added implementation guidance and references to AWS-LC library and KMS services for cryptographic algorithms

Security assessment

Enhanced documentation about security features (cryptographic implementations) by adding references to AWS-LC and KMS. No vulnerability fix, but improves security guidance.
