[Mono-dev] Verifying XML Sign

[Atsushi Eno]

Hi,

The sample code I put runs on .NET 1.x if you use Mono.Security.dll
which could be used under .NET 1.x too. On the other hand, 
X509Certificate2 is sure, only 2.0 thing, but I just use it as a
shortcut to retrieve AsymmetricAlgorithms from certificates.
