(MFC) MD5 Hash a String (such as a password string)

Demonstrates how to MD5 hash a string to get MD5 hash in hex encoded string representation. (The MD5 hash is 16 bytes, and therefore a hex encoded MD5 hash would be 32 chars.)

    const char *password = "myPassword";

    CkCrypt2 crypt;
    crypt.put_HashAlgorithm("md5");
    crypt.put_EncodingMode("hex");
    const char *md5Hex = crypt.hashStringENC(password);
    strOut.append("MD5 hash (as a hex string) = ");
    strOut.append(md5Hex);
    strOut.append("\r\n");

    // The hex string will be uppercase.  Your application
    // can easily convert it to lowercase if desired via non-Chilkat means.
