AWS payment-cryptography documentation change

Service: payment-cryptography · 2025-05-10 · Documentation low

File: payment-cryptography/latest/userguide/use-cases-issuers.networkfunctions.mastercard.md

Summary

Updated example KeyArn to full ARN format and added example KeyCheckValue in response documentation

Security assessment

The KeyCheckValue addition demonstrates how to validate cryptographic key integrity, which is a security feature. However, there is no evidence this addresses a specific security vulnerability. The change improves clarity for a security-related field but does not resolve an existing issue.
