    <summary>Managed implementation of the Digital Signature Algorithm (DSA) algorithm. </summary>
    <remarks>
      <para>In Mono this class is completely implemented in managed code.</para>
      <para>A major design difference between Mono and Microsoft implementation is the key generation. Microsoft always generate a new key pair in the constructor (unless a <see cref="T:System.Security.Cryptography.CspParameters" /> object is used with an non-empty container). This can degrade performance (e.g. server) when key pair are imported (e.g. XML) after the object is created. Mono implementation doesn't generate a new key pair until it is required (e.g. exporting, signing, encrypting ...). This shouldn't affect functionality but you may experience slowdown (during key pair generation) at a different time than MS implementation.</para>

          <example>
            <code lang="C#">
bool IsPrivateKeyAvailable (DSA dsa)
{
	if (dsa == null)
		throw new ArgumentNullException ("dsa");
	try {
		DSAParameter p = dsa.ExportParameters (true);
		// private key is available - now zeroize it from memory
		Array.Clear (p.X, 0, p.X.Length);
		return true;
	}
	catch (CryptographicException)
		// private key wasn't available
		return false;
	}
}
  </code>
          </example>
          <para>You are responsable to zeroize the private key (<see cref="T:System.Security.Cryptography.DSAParameters" />.<see cref="M:System.Security.Cryptography.DSAParameters.X" />) if you export it from the instance.</para>
