Document Access Servlet
Available from Information Security Magazine
ISC’s Document Access Servlet (DAS) is a customer-hosted web service that performs asymmetric private key operations (such as decryption, signing, or key agreement) on behalf of properly authenticated users. Typically the users are members of a group that may be thought of either as a community of interest (COI) or as defining a particular security role. DAS 1.8 provides server-mediated RSA and ECDSA signing and ECDH key agreement as well as RSA decryption services, and is fully compatible with DAS-enabled CSPid 2.0 and above.
