NetMF 4.2 and PKI

Hi kiwi65,

Netduino Mini doesn't support this style of encryption. There was some early non-open-source crypto in NETMF (and there was even support for the early version of XTEA)--but to get a true crypto solution with NETMF you're really looking for a higher-end MCU running OpenSSL, etc.

Has anyone had experience/success getting PKI encryption working on a Mini?

It seems like the Mini's version of NetMF has classes like 'System.Security.Cryptography.X509Certificates.X509Certificate2' and 'Microsoft.SPOT.Cryptoki.Session' pretty much stubbed out.

Any time these are invoked they generate:

An unhandled exception of type 'System.NotSupportedException' occurred in Microsoft.SPOT.Security.PKCS11.dll

Any takes? Any example code?

Thanks in advance

Chris/Anyone, does the Mini support PKCS#11?

Because we're having no luck creating Sessions, or enumerating Slots. We get 'NotSupported' exceptions.

All we really want to do is encrypt (RSA) from a public key that's within a X.509 certificate.
