설명

API 키, 인증서 등 민감 데이터 암호화를 위한 유틸리티와 E2EE 요청/응답 처리를 구현한다. (ENC-01, ENC-02, ENC-03)

📌 참조: Documents/Security.md §4 (E2EE 전송 암호화), Documents/ProgramSetup.md §7.3 (SecureTransport Action Filter)

체크리스트

  • SPMS.Infrastructure/Security/AesEncryption.cs — AES-256-CBC 암호화/복호화
  • SPMS.Infrastructure/Security/RsaEncryption.cs — RSA-2048 키 쌍 관리
  • SPMS.Infrastructure/Security/E2EEService.cs — 하이브리드 암복호화
    • EncryptedKey 복호화 → AES Key 획득
    • RequestCipher 복호화 → 평문 데이터
    • ResponseCipher 암호화 → 응답 암호문
  • SPMS.Infrastructure/Security/TimestampValidator.cs — 타임스탬프 검증 (±30초)
  • SPMS.API/Filters/SecureTransportAttribute.cs — Action Filter 구현
  • 빌드 성공 확인
