Encrypt String in java and decrypt it in winrt c#

Question

How one would encrypt a string using symmetric/asymmetric decryption on WinRT Metro in C# and encrypt this in java, let's say in a webservice?

I want to use RsaPkcs7 algorithm and I can see that CryptographicKey class and RSAParameters class are not even near compatible.

How this could be accomplished?

Answer 1

There is an example in MSDN and I made a Java port of it.
