1. A method in a server or servers, or other computing device or devices each including a processor and memory, which provides an integration of security and/or cryptographic functions which may include one or more applications such as: public key infrastructure, privilege management infrastructure, certification authority, registration authority, attribute authority, hardware security module, and/or other hardware systems and/or software systems and including a method that communicates with one or more of these applications, which together may be described as a platform service and be capable of supporting a variety of security-related functions; such as to enable the extension of security credentials for entities such as enterprise businesses, government, small business, individuals, systems integrators, independent software vendors and others, in order to effectuate more secure communication between one such entity, which may be referred to as a user, and one or more such remote third party entity, which also may be referred to as a user, with an example of such being from an enterprise entity to a third party customer entity of that said enterprise entity which will likely exist beyond that said enterprise entity's network firewall; such that to access, utilize and/or benefit from the security and/or authentication capabilities of said applications and/or said platform service, such a said entity need not have specific knowledge and/or expertise regarding typical technical requirements, operation and/or capabilities of how said cryptography and/or security systems function, operate and/or perform and/or accomplish their functions in order for said entity to achieve the security needs, features and/or functions provided by said platform service; such that an entity might access, utilize and/or benefit from the capabilities of said platform service through the use of an application programming interface which could access and/or utilize designated capabilities of said platform service to said entity in a fashion that could require substantially less technical knowledge of security and/or cryptography systems of the part of said entity than might otherwise be required in order for said entity to achieve its desired security-related controls and/or results; such that such platform service may integrate with existing security and/or cryptographic applications pre-existing with an entity and therefor not require such pre-existing application as a component of said platform service.
