AD CS Key Archival and Recovery

Applies To: Windows Server 2008

Active Directory Certificate Services (AD CS) requires key recovery agent certificates, exchange (XCHG) certificates, and keys in order to support key archival. The functioning of key recovery agent certificates, XCHG certificates, and the cryptographic service providers (CSPs) needed to create them is critical to a public key infrastructure.
