The Problem: One problem in the past with the DoD PKI infrastructure was the inability to recover Common Access Card (CAC) private encryption keys and certificates that were either expired or revoked. This becomes necessary when a CAC is lost and its certificates are revoked or when a CAC and the certificates it contains simply expires and is surrendered to DEERS/RAPIDS before the users encrypted emails have been decrypted.

An Auto Key Recovery capability has been fielded by DISA to permit holders of new CACs to retrieve encryption keys/certificates from previous cards to permit decryption of old email. ISEC: Excellence in Engineering The Solution: Steps to Recover

Private Encryption Keys The following slides identify steps to recover private encryption keys, escrowed by DISA, from CACs that do not have the Auto Key Recovery functionality. ISEC: Excellence in Engineering URL for Key Recovery https://ara-1.c3pki.chamb.disa.mil/ara/Key

Or https://ara-2.c3pki.den.disa.mil/ara/Key This is the Automatic Key Recovery URL. Note: The URL address shown above is case sensitive . When you go to this link, you must identify yourself with PKI credentials. Use ONLY your identity certificate! ISEC: Excellence in Engineering

At this time open the URL https://ara-1.c3pki.chamb.disa.mil/ara/Key Or https://ara-2.c3pki.den.disa.mil/ara/Key ISEC: Excellence in Engineering Choose Your
