About the topic called 'Porting Java Public Key Hash to C# .Net'

See more:

Java

.NET

I have read this topic, it's wonderful.:thumbsup:

But I just have a reverse process about of this topic. The keys (public and private) were generated by .Net platform, I want to decode the public key to encrypt a text and then send it back to the .Net platform to decrypt it.

I can not convert the string of public key to Java public key. I have found many materials and it looks like the string of public key was generated with some random value by .Net platform.

What should I do with the string?

Thanks.

Below is the errors when I try to get the public key:
