Ciphers (#17 )

* add AES.java additions + Galois.java * desc used ECB and ECBExceptionless instead of seperate interfaces. AESECB done * Twofish ECB developments, moved some files * twofishecb done * Update Factories.java factories.java topology rewrite 👍 * Update Factories.java fix whitespace + forgot to add AriaGCM + SerpentGCM * desc RC6ECB.java placeholders, LE32.java * encblk+decblk funcs * RC6 done * desc - move Camellia to seperate - create CamelliaECB (it sucks, will fix it more after) * good fixes! * Rmv 16bfix (#14) * progress some progress was made. next commit will be working on Aria.java (its large so may take some time) * "invalid config" * Update Aria.java potential working! * bugfix * Sha224 fix (#15) * Update SHA224.java potential fix * Update pom.xml tested - works now! the entire fix was adding * 8L to the padding calculator thing xD * SHA384 is working LESGO! * Create SHA512.java * Sha512 impl (#16) * desc * Update SHA512.java * Update SHA512.java oookay a bit of opencode and a lot of time later its solved!

+A multi-purpose Cryptography library in Java. Working on it day by day, slowly. Someday this will be complete, today is not that day.
+To be clear, this is **NOT** mean't to be a replacement/alternative to BouncyCastle. Instead, it is meant to include what BouncyCastle does not have. No code was taken from OpenSSL or BouncyCastle for that reason.
+
+### Current Objective: ZekerRijndael (custom encryption sub-library)
+
+Use `setopt interactivecomments` (zsh only) to allow using `#` for comments if you see errors like `zsh: command not found: #`
+
+Ensure Java + javac are installed, on MacOS it can be installed with Homebrew by running `brew install openjdk`
+
+You will also need maven installed. With Homebrew, this can be installed with `brew install maven`.
+
+To compile (these commands should work universally):
+
+1. git clone https://github.com/Geprivilegieerde-Anonimiteit-BV/XACrypto.git # download the git repository
+2. cd XACrypto # enter the directory
+3. mvn clean package # compile the package cleanly
+
+You should find the built jar at target/XACrypto-1.0-SNAPSHOT.jar

Xiao X	413b038b8a	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	2026-06-02 12:34:10 -04:00

Xiao X	44859407cf	Sha256 > Main (#1 ) * Update SHA256Advanced.java ByteFromHex function * OH MY GOD 45 mins of coding. my brain hurts lol. its likely i will move sha256 to its own package inside of hash as Digest and several other classes will be included in it so instead of plopping them inside of misc i think ill use a standalone package. thanks for reading my rant * several sha components finally made sha256 standalone package, added classes: HMAC HKDF (placeholder for now) Hex Digest too but i did that last night * desc maybe it done * Update README.md * COMPLETION! XACrypto\SHA256 is officially finished in its entirety. I might still make more modifications tho lol * Update XACrypto.java yippie! i made a dumb mistake * bug fix TWO. GOD. DAMN. CHARACTERS. completely messed up the end hash. i used 0 instead of i inside a for loop. i want to die :) * remove tests + update README + good riddance garbage messagedigest sha256 yip	2026-05-27 19:01:40 -04:00
