Interfaces for combining calls in an emulated environment

An apparatus, comprising:

• a host operating system executing on at least one CPU of the apparatus, the host operating system including at least one security module;
• an emulated environment executing in the host operating system;
• an application executing in the emulated environment for performing secure shell communications;
• and
• an interface between the emulated environment and the security module, in which the interface translates calls from the application in the emulated environment to calls to the security module in the host operating system, and in which the interface combines a first call to generate an encryption key and a second call to generate an encryption key from the application into a single combined call to the security module during the secure shell communications.

A computer program product for providing secure communications to an application in an emulated environment, comprising:

• a non-transitory computer-readable medium comprising:
• code to process secure shell communications;
• code to receive a first call to a security module located outside an emulated environment during the secure shell communications, the first call comprising a request to generate an encryption key;
• code to receive a second call to the security module located outside the emulated environment during the secure shell communications, the second call comprising a request to generate an encryption key;
• code to combine the first call and the second call in a combined call;
• and
• code to execute the combined call to the security module located outside the emulated environment.
