DRAFT CHEAT SHEET - WORK IN PROGRESS

Introduction

This Key Management Cheat Sheet provides developers with guidance for implementation of cryptographic key management within application in a secure manner.

Key Management General Guidelines and Considerations

Algorithm Selection

Selection of the cryptographic and key management algorithms to use within a given application should begin with an understanding of the objectives of the application. For example, if the application is required to store data securely, then the developer should select an algorithm suite that supports the objective of Data-At-Rest (DAR) security. Applications that are required to transmit and receive data would select an algorithm suite that supports the objective of Data-in-Transit security. We have provided recommendations on the selection of crypto suites within an application based on application and security objectives.
