Zeker rijndael (#10)

Browse Source 
* Update README.md (#2)

* AES128.java + UnchangedData.java

* Several ciphers, alot of ZekerRijndael progress

* maak de j0-functie aan

* maak een inc32-functie aan

* progress!

* GCM.java complete!

* my dementia .. lol

* SM4 COMPLET!

* decryption bugfix

* easy

making these were so easy, just had to copy and paste AES128 and change like 5 numbers

* read desc

i feel sick. i made the rest of the functions dummy functions and will finish them in the future. i am unsure if i will continue working on this tomorrow, i may take a break or i may not, who knows.

* F func finished in Camellia. several bugfixes

feel much better btw, took a shower and slept :)

* FL don

would recommend deleting .idea when you clone. FL done

* Camellia

Camellia complete

* add factory

* bugfix,more consise

* Fixed very annoying seperate AES<bitcount>.java files into one unified AES.java file :D (#4)

* AES.java potential

* Update AES.java

bufxie

* remove old libs

removed old AES$.java files as they are deprecated now that AES.java is created. (AES.java should be 100% functional.)

* Update Factories.java

aaand rename the AES128 factory to use AES with bits:128 instead of AES128

* Update AES.java

Performance Enhancements

PKCS#7 OK!

Safety (missing bounds protection)

* Update README.md (#5)

* Update AES.java

ah yes i love things magically stop working after PR ! :P

* something idk

my head is hurting again! :D so fun. i might make AESGCM.java use GHASH.java's xor function if i can figure out why its not working. also AESGCM.java (in its current state) sucks. i need to work on it a bit but just not now.

* update gitignore

* uh

how did it break? i didnt even change either of those files since they were working

* very legit solution 4realz1

* useless

* fix (#7)

* GHASH compnonce + fixed AESGCM bugs

* Update AES.java

some fixes.

* Update AESGCM.java

add warning

* Camelia

performance enhancements + decryption (i forgot to add it before lol) + several bugfixes

* "It's not a disaster, It's innovation!"

* decryption + bufixes

* Update Project_Default.xml

* this isnt English class

* Update README.md

it duplicated itself lol

* desc

Aria.java progress, next commit will have GRK finished

* Aria.java complete!

* desc

added support for Camelia 192 + 256 bit operation, perf enhancements and bugfixes

* add ARIAGCM factory

my wrapper in ARIAGCM handles GCM :)

* Update README.md

add TODO

* added 128,192,256 support for AESGCM

* desc

soo... did you know sometimes you actually do want to reuse code without getting 68 warnings from intellij?

* note+camellia tab

* began Serpant.java

* Serpent COMPLET!

* desc

add dummy functions to twofish

* Update Twofish.java

progrses on twofish + HUMOR

* twofish done + readme upd

* HOLY

i actually finished Blowfish.java lol, almost done with ECB, just neeed 2 functions

* Bfish ECB done! :D

* desc

- fix typo

- add Aria.java support for Aria-ECB

- move Aria.java to globalpackaeg

* Create AriaECB.java

will finish this tmr. im so tired lol

* desc

ariaecb complete, also forgot to add factories for blowfish too

* Update AriaECB.java

* sm4ecb complete
