Problem following bouncy castle example

[Lester D Jones]

Hello

I am following an example to implement bouncy castle to encrypt data coming out of a midp to servlet.

On the servlet I have the following line: Digest digest = new SHA1Digest();
I cannot compile because i get the following error: type mismatch cannot convert from SHA1Digest to Digest.

Digest is an interface and not a class. How can I go around this?

The SHA1Digest is a BC specific class. If you are going to use the light-weight library on both ends, then you can either import the correct Digest class or use the JCE equivalent ;

MessageDigest digest = MessageDigest.getInstance("SHA1", "BC");
