    I'm kinda going blind with a lot of this API stuff sometimes because C examples are rare for most anything 400. Anyway I can't get a MD5
    thing to work and return the right hash. Anyone have a real working example? I was careful to make sure my data was ASCII since most if
    not all MD5 test vectors assume ASCII.

    // Test string, minus quotes, CCSID 819.

    I am trying to do the SHA-256 hashing from a file from the IFS. The hashing is not coming our correctly. Can somebody help?
