Abstract

A system that supports cryptographic web services is provided. A program running on program computing equipment may call a local cryptographic function. A web services interface such as a simple object access protocol interface on the program computing equipment makes a corresponding remote cryptographic function call to a web services interface such as a simple object access protocol interface at a cryptographic web service over a communications network such as the internet. At the cryptographic web service, a cryptographic engine implements cryptographic operations such as encryption and decryption operations. After successful authentication of the calling program, the cryptographic engine produces results for the remotely cryptographic function and returns the results to the program over the communications network.
