We Solve Dssenh.dll Error Problems

The software Windows Server 2003 Enhanced DSS and Diffie-Hellman Cryptographic Provider is a general-purpose cryptographic module. This CSP runs on a single DLL the dssenh.dll module which encapsulates several different cryptographic algorithms.

Given that it is a FIPS 140-2 Level 1 compliant cryptographic module the DSSENH offers software developers an easy-to-use cryptographic service that passes government-imposed export restrictions on cryptography. The dssenh.dll file implements the Diffie-Hellman key exchange, hashing or message digests, data signing and signature verification.

The SHA and DSA algorithms are adapted to process application requests.

The dssenh.dll file comprises the DSSENH module’s logical boundary. It sets the enclosure of the computer system on which the cryptographic module is to be executed. It thus defines the components of the cryptographic module and structures its physical configuration as a Multi-Chip standalone module.

Such physical configuration of the DSSENH is defined in FIPS PUB 140-2 where it is noted that the module does not include Data Protection API. Thus data protection is not supported by the DSSENH in Microsoft Windows Server 2003.

The dssenh.dll file – the user and cryptographic officer roles as defined in FIPS PUB 140-2 extends two main functions of the DSSENH. The dssenh.dll file to generate keys may implement services offered by both roles.

Such keys may be used or deleted per request of the application. No specific key is associated with a user and users may own numerous keys. Different keys are assigned to different users in both signature and key exchange.

The DSSENH module runs only on a single-user mode. As such it does not support multiple concurrent operators. Every single process that requests access is channeled through the dssenh.dll file to be given its own instance of the module. This way each process is given access to all information and keys contained in the dssenh.dll file.

This means that the operator or user is given full access to security items within the module when it requests access. Consequently upon detachment from the DSSENH module, keys or other information placed in the module will not be stored.

What is a DLL?

Your operating system comes pre-installed with Microsoft DLL’s and most third party programs also install DLL’s.

DLL (Dynamic Link Library) is Microsoft’s implementation of the shared library concept. Meaning there’s a DLL library on your computer and each DLL can be shared among different Microsoft and third party programs. This shared library method helps your computer run faster by having fewer operations running at the same time.

When a DLL is missing or corrupt it may show an error message and programs may fail or crash.

Because DLL’s are shared, one missing or corrupt DLL may affect multiple programs on your computer.
