US Classification:

713155, 713153, 713150

Abstract:

This application generally describes techniques for dynamically updating trusted certificates and CRLs, generally referred to herein as certificate information. That is, techniques are described for updating trusted certificates and CRLs without terminating existing communication sessions. An exemplary method includes the steps of receiving an initial configuration that includes a trusted certificate authority, receiving certificate information that includes a certificate revocation list (CRL) and a first certificate from the trusted certificate authority, storing the certificate information in the configuration, initiating a communication session for an application, receiving an update to the certificate information, and updating the configuration to reflect the update to the certificate information without terminating the communication session. A computing device may receive the update to the certificate information from a user, as well as receiving a command from the user to apply the update to the certificate information to current communication sessions.

Abstract:

Techniques are described for mapping an emulated SSL implementation to, for example, OpenSSL. An exemplary method includes receiving a request to initiate a communication session from an application, running in an emulation environment, with a first SSL API of an emulated SSL implementation running in the emulation environment, sending the request to a communication interface process that is running in a base computing environment, wherein the emulation environment is a process running on the base computing environment, extracting, with the communication interface process, communication session information from the request, calling, with the communication interface process, procedures provided by a second SSL API of an SSL implementation, in accordance with the request, to initiate a communication session with a computing device, wherein the SSL implementation is a program running in the base computing environment, initiating the communication session with the computing device, and transferring data to the computing device.
