# File changes

- Libraries:
  - Update lib/logger to latest artifact
  - Update lib/userio to latest artifact
  - Rename lib/basicUserIO -> lib/userio

Ciphers.Subclasses.Polybius:
- Fix issue where digits could not be part of 6x6 tables
- Rename polibius to have 6x6 in the name
- Add 5x5 table support
  - 5x5 table letter replacement (defaukt J->I) can be customized

Ciphers.Subclasses.Shift:
- refactor rename variables

Ciphers.Adfgvx:
- Replace private modifiers to protected for variables that are accessed by Junit tests
- Add feature that the keyword for the polybius square can not contain digits

Ciphers.Ciphers:
- Add initialize encrypt and decrypt method to interface
- Add OutOfMemoryError for setFileWriteMaterial
- Fix issue where InformationFiles were not visible by neither the compiler nor the jar, resulting in printInformation() to be excluded
- Add setKey() for ciphers to easily set keywords

Main:
- add try finally block to avoid printStackTrace when Ctrl<c> the program

Menu:
- Add path change of maven hierarchy
- Make list of unwanted classes to loop through and filter

===User===
- no new changes

===Developer===
- Refactor hierarchy for Maven
- Add JUnit5 and basic Cipher tests
    - Note: Make derived cipher fields protected if needed access by JUnit tests

Master:
- Allow to set Logger level via Main.java

Ciphers:
- setkey(), method to set int variable, is in abstract cipher class

- Allow JAR File support. 
    - Fixing a bug where a JAR file cannot be built from the project. Code cleaning is needed in ClassFinder.java.
    - Fixed a bug where the method 'printInformation()' is not added when the cipher's constructor is missing. When 'informationList' is set but 'information' is not set, the method was excluded.
    - Add Jar support for information text files.
- Add Cipher: Rot13
- Add Logger. For each class: If you want to log, use `Cipherlogger.LOGGER.log() or any other calling method form java.util.logging`
- Fixed a bug where the method 'printInformation()' is not added when the cipher's constructor is missing. When 'informationList' is set but 'information' is not set, the method was excluded.
- Public methods in Ciphers.Ciphers.java that are only meant to be invoked by the menu and not called by a specific cipher (e.g. startCryption() and setInformationFile()) are now only accessible by invoking. That way, if one of these methods is accidentally called, the program handles this issue. If, from a specific cipher, the method is for some reason invoked, this will still give an error. But this implementation is to handle accidental method calling.
- Move Shift method from Caesar to Subclass for future Rot13 implementation

- Small changes:
    - Add issue page references to README.md to encourage ticket creation.
    - Add cipher information for Caesar and Rot13
    - Rename Cipher interface method 'addInfoToOutputFile()' to 'writeAdditionalInfo()'
    - Add .gitignore
    - Update issue templates
    - Update readme to add Setup (Instructions)
    - Add Run.bat for releases

Ciphers:
- Add header of 20 to encapsulate 'printInformation()' when having multiple lines.
- Reworking Cipher.java to diminish public methods (so that these methods cannot be called from a specific cipher. Some methods are meant to only be run by the main code (menu.java)).
- Add custom exception to prevent public Ciphers.Ciphers.java classes to be called by specific ciphers. It may only be invoked by other classes like menu.java or write.java

Caesar:
 - Fix a bug where the input is changed after shifting. Java is not entirely pass by value after all.
 - Add writing shift to output file.
 - Reworked code a bit.
 
ClassFinder:
 - Jar file of the project can now successfully be built.

Write:
 - Prepend filename to output.txt

WriteHelpers:
- Add writeInteger to write a number to the output file

Menu:
- Allow ciphers to have classes that will not be added to the menu, like a nested exception class.
- Add log.
- Add JavaDoc

- Add own basicUserIO library as a submodule.
    - Replace local library java file with submodule library.
    - Update code to adjust using basicUserIO library.
- Add flow diagram .xml
- Update README.md

Write:
- Remove 'repeat' operation to support Java 1.8

WriteTables:
- Fix a bug where a dualheader with char[] yHeader does not have a correct horizontal line length.

Add package Ciphers/InformationFiles. Add text files that match the name of a cipher to add multiple lines with ease to the 'printInformation()' method
- Cleaned up warnings

Menu:
- Checks if information file exists. If <CIPHERNAME.txt> exists within the Ciphers/InformationFiles package that matches invoked <CIPHERNAME>. Add 'printInformation()' method to the menu that prints text-file. If not exist, use String 'information' set in the cipher's constructor instead. If both do not exist, exclude 'printInformation()' from the menu.

Ciphers:
- Set 'informationList' for 'printInformation()' if Ciphers/InformationFiles/<CIPHERNAME.txt> textfile exists. Set information for 'printInformaiton() if textfile does not exist and 'information' is set in the cipher's constructor. If neither exist, exlude 'printInformation()' from menu.
- Add JavaDoc

Adfgvx:
- Add write xHeader and yHeader to polybius square.

Porta:
- make some variables final.

- Group cipher algorithms into their own classes in Ciphers.Subclasses. Being Polybius.java, Substitution.java, ColumnarTransposition.java
- Add WriteTables.java, an extensive class so that all types of tables can easily be written by all ciphers. char[], char[][], int[] and int[][] arrays can be added as headers in any combination.
- Add WriteHelpers.java, this might be temporary

Ciphers:
- Resolved an issue where cipher specific data is written twice if it contains any data 'addInfoToOutputFile()'
- Add JavaDoc
- Add helper methods for ciphers. This might be moved to its own SubClasses classfile later

Adfgvx:
- Moved cipher algorithms to Ciphers.Subclasses so that they can be re-used by other ciphers
- Renamed translate table to substitution table.

Caesar:
- Remove accidental test method

Porta:
- Clean up

- Feature #4 added, add methods to package 'Subclasses' and add import Ciphers.Subclasses.CLASSNAME to main cipher
- Feature #5 added, any public methods in a main cipher class will automatically be added to the method list when that cipher has been selected.
- Add javadoc comments
- Optimalized code
- Code now always calls selected method via the parent method (Cipher.java) for more structure. This prevents methods getting called from multiple classes (not more in Menu.java).

ClassFinder:
- Change parameter method *find* from String array to String list, this is to add an unknown amount of unlisted classes to filter

Main:
- Remove unused import

Menu:
- Improve imports
- Made code cleaner
- Better naming of variables and methods
- Made cipher methods local variable in executeCipher()
- Less parameters

Ciphers:
- Better naming of method
- Remove unused constructor
- Group called methods by return type
- Optimalized code

**Available Ciphers:**
- Caesar
- Adfgvx (Encipher)

**Bugfixes**
- Fix an issue where the output of the Adfgvx cipher was incorrect
- Fix various line spacing in CMD

**Added features**
- Adfgvx file writer expanded, now prints all tables

Add Cipher: Adfgvx (Encrypt)
Re-add output file writer function
Add new ciphers interface method for adding writing material to the file writer

Caesar cipher
Code is dynamic
