I think there's something wrong in your question. SHA2 (generally SHA256 to 
SHA512) is definitely supported in mono.

Your error message does say " Unsupported hash algorithm: 
1.2.840.113549.1.1.11" and the OID does map to sha256WithRSAEncryption, but the 
problem is in Mono.Security.X509.X509Certificate, which is all kinds of messed 
up, and barely functional at all. I have not heard of anyone working on it - 
but that doesn't mean they're not.

If I'm not mistaken, iFolder is not actively maintained, right? That would be a 
problem. Yes, there is a limitation of mono in the brokenness of 
X509Certificate, but assuming that's not going to be fixed anytime soon, the 
iFolder developers will basically need to find a way to workaround the 
problem...
