** What are DH/DSS keys?

:END:
PGP uses a different name for the former default encryption
algorithm Elgamal: They name it DH, which usually stands for the
Diffie-Hellman key exchange algorithm. It has been said that this
had historic patent and business reasons. It is however exactly
the same thing as the Elgamal algorithm.
They also use the acronym DSS (Digital Signature Standard) instead
of the DSA (Digital Signature Algorithm). The difference is that
DSS requires the use of certain hash algorithms; however OpenPGP
allows the use of more than those hash algorithms, thus GPG usually
uses the term DSA.
