Zeker rijndael (#10)
* 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
