Hello John,
I've never been able to make OAEP works under Windows 2000 (even with the
high encryption pack installed) but never had problems with XP.
The Mono's (http://www.go-mono.com) implementation of
RSACryptoServiceProvider is totally managed and doesn't have any
restriction, e.g. it can EncryptValue/DecryptValue and be used with both
PKCS1 and OAEP padding. In theory you should be able to use the Mono's
RSAManaged class (used by RSACryptoServiceProvider) with Microsoft's
RSAOAEP... classes under Windows but I never tried it (however using
RSAPKCS1... classes will not work due to a framework bug in
PKCS1MaskGenerationMethod).
