<summary>Abstract base class for all implementations of the Digital Signature Algorithm (DSA) algorithm. </summary>
<remarks>
<para>There is a serious bug in version 1.0 and 1.1 of the .NET framework. The constructor for DSA was declared internal (not protected) this makes it impossible to inherit from the DSA class outside the mscorlib.dll assembly (which is quite limiting).</para>
<para>More information about DSA can be found in NIST FIPS PUB 186-2: Digital Signature Standard (DSS) available at http://csrc.nist.gov/publications/fips/fips186-2/fips186-2-change1.pdf
