The above is a Java class,
I'm over here is the c # and the.net framework, you need to post an interface, the interface is a Java implementation, but the found, a parameter is to encrypt, use a class is shown above, now I'm stuck in the messageDigest. Digest () here, sha256 can implement these have a similar way, but I'm looking for a long time, do not fall messageDigest. Find digest () is implemented in c #,
Dear bosses, sincere, boy grateful,

Can be replaced by

 
The Convert. ToHexString (hashValue)

Excuse me, whether need to consider the byte [] of JAVA and c #, is not the same as the scope? Because the Java byte is - 128-127

Hex is the same
