9. On the Configure Cryptography for CA page, keep the default settings for CSP (RSA#Microsoft Software Key Storage Provider) and hash algorithm (sha1), and determine the best key character length for your deployment. Large key character lengths provide optimal security; however, they can impact server performance. It is recommended that you keep the default setting of 2048 or, if you deem it appropriate for your deployment, reduce Key character length to 1024. Click Next.
