SE 470 PROJECT SPRINT 1

Definition: A program will be written to measure agility.

Agility: Agility is how much you apply agile concepts to software development. If you apply agile principles, you should discover the problems earlier and you should solve those problems immediately. As a result, the customer satisfaction would be accomplished.

The project will be developed in teams. Each team will use a different base string and produce special strings. The special strings will have a SHA-256 hash value starting with a secret code string. The aim is to produce maximum number of correct special strings. The secret code will be announced in the class.STUDENT EDIT WHO ASKED THIS ON CHEGG.COM: HERE YOU CAN ASSIGN A RANDOM SECRET CODE ARBITRARILY

For each team, there are 2 types of correct special strings. The first type string is correct, if it is a SHA-256 hash value starting with the secret code. The second type string is correct, if its first type part is correct and as a whole it has a SHA-256 hash value starting with the secret code. The following sentences summarize the special strings.

For the Team N:

Base string: TEAMSTORY

Special string type 1: TEAMSTORY+

Special string type 2: < Special string type 1>DONE+

: a digit = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] = [0-9] + : one or more digits

Example for Team 5:

Base string: TEAM05STORY

Special string type 1: TEAM05STORY+

Special string type 2: < Special string type 1>DONE+

Here is an example program to get SHA-256 hash value for Team 5:

import java.security.MessageDigest; import java.util.Arrays;

import java.util.Date;

public class Agility {

public static void main(String[] args) { String base = "TEAM05"; int count = 0;

while (true) { count++;

String trial = base + "STORY" + count; String trialHash = getSHA256Hash(trial); if (trialHash.startsWith("SECRET CODE"))

PrintLineToFile(trial, "Agility.txt");

}

}

public static String getSHA256Hash(String data) { try {

MessageDigest digest = MessageDigest.getInstance("SHA-256"); byte[] hash = digest.digest(data.getBytes("UTF-8"));

return bytesToHex(hash); } catch (Exception ex) {

ex.printStackTrace();

}

return null;

}

public static String bytesToHex(byte[] bytes) { StringBuffer stringBuffer = new StringBuffer(); for (int i = 0; i < bytes.length; i++) {

stringBuffer.append(Integer.toString((bytes[i] & 0xff) + 0x100, 16).substring(1));

}

return stringBuffer.toString();

}

}
