CrypterPK uses the new Whidbey X509Store and X509CertificateEx classes to encrypt/decrypt files.

You can choose certificates from the Windows Certificate Store (MY and AddressBook) to encrypt the file. You can even choose multiple certificates. just like in PGP.

I think that’s a feature that was missing in EFS. Who wants to write a shell extension for this ?

Compiled against Visual Studio 2005 Beta 1 but should be trivial to backport to .NET 1.1 and CAPICOM. CrypterPK.zip (46,24 KB)
