The uses an algorithm that is designed to provide only the digital signature function and cannot be used for encryption or key exchange.

Digital Signature Standard (DSS)

Explanation:

The term that is being described is known as Digital Signature Standard (DSS). This term is mainly used in the context of cryptography and was created by the Federal Information Processing Standard(FIPS) in order to define algorithms that are used to generate digital signatures using a specifically designed Secure Hash Algorithm(SHA) to authenticate electronic documents.
