[Solved]Java Hello M Issues Building Functional Code Final Work Java Basically Authentication Aut Q37141203

JAVA ONLY!!!!!

Hello There!! I’m having issues building out the functional codeto my final work(JAVA). It is basically anAuthentication/Authorization program to validate a userscredentials. Below will ill place the actual instructionsand my PSEUDOCODE, which could be edited if anyone sees fit, butthe code should follow the logic I built out

Option 1: Authentication System For security-mindedprofessionals, it is important that only the appropriate peoplegain access to data in a computer system. This is calledauthentication. Once users gain entry, it is also important thatthey only see data related to their role in a computer system. Thisis called authorization. For the zoo, you will develop anauthentication system that manages both authentication andauthorization. You have been given a credentials file that containscredential information for authorized users. You have also beengiven three files, one for each role: zookeeper, veterinarian, andadmin. Each role file describes the data the particular role shouldbe authorized to access. Create an authentication system that doesall of the following:

 Asks the user for a username

 Asks the user for a password

 Converts the password using a message digest five(MD5) hash o It is not required that you write the MD5 fromscratch. Use the code located in this document and follow thecomments in it to perform this operation.

 Checks the credentials against the valid credentialsprovided in the credentialsfile o Use the hashed passwordsin thesecond column; the third column contains the actual passwords fortesting and the fourth row contains the role of eachuser.

 Limits failed attempts to three before notifying theuser and exiting theprogram

 Gives authenticated users access to the correct rolefile after successfulauthentication o The system information storedin the role file should be displayed. For example, if a zookeeper’scredentials is successfully authenticated, then the contents fromthe zookeeper file will be displayed. If an admin’s credentials issuccessfully authenticated, then the contents from the admin filewill be displayed.

 Allows a user to log out

 Stays on the credential screen until either asuccessful attempt has been made, three unsuccessful attempts havebeen made, or a user chooses to exit

You are allowed to add extra roles if you would like tosee another type of user added to the system, but you may notremove any of the existing roles.

PSEUDOCODE:

WHILE attempts EQUALS 3 OR LESS

     GET username

     GET password

     CONVERT password (usingMD5hash)

     READ credentials

   ELSE

      Give user access tofiles

   ENDFOR

     Notify user and exitprogram

   IF credentials = Zookeeper

       PRINT files relatedto Zookeeper

   ELSEIF credentials =Veterinarian

       PRINT files forveterinarian

   ELSE

       PRINT files forAdmin

ENDFOR

Shut down program.
