From 544e51ff6ba0973336f89e4b2b914679d1547458 Mon Sep 17 00:00:00 2001 From: yet300 Date: Fri, 8 May 2026 17:19:07 +0400 Subject: [PATCH] Refactor: Convert SHA-256 and SHA-512 to pure Kotlin for KMP - Translated `SHA256MessageDigest` and `SHA512MessageDigest` to Kotlin. - Removed `java.util.Arrays` and `System.arraycopy` dependencies, using Kotlin's native `.fill()` and `.copyInto()`. - Refactored legacy `while` loops into idiomatic Kotlin `for` loops. - Improved variable scoping in the `transform` function by declaring local variables at the point of use. --- .../southernstorm/crypto/RijndaelAES.java | 1099 ----------------- .../crypto/SHA256MessageDigest.kt | 403 +++--- .../crypto/SHA512MessageDigest.kt | 438 ++++--- .../southernstorm/crypto/package-info.java | 12 - 4 files changed, 400 insertions(+), 1552 deletions(-) delete mode 100644 app/src/main/java/com/bitchat/android/noise/southernstorm/crypto/RijndaelAES.java delete mode 100644 app/src/main/java/com/bitchat/android/noise/southernstorm/crypto/package-info.java diff --git a/app/src/main/java/com/bitchat/android/noise/southernstorm/crypto/RijndaelAES.java b/app/src/main/java/com/bitchat/android/noise/southernstorm/crypto/RijndaelAES.java deleted file mode 100644 index a34d07c2..00000000 --- a/app/src/main/java/com/bitchat/android/noise/southernstorm/crypto/RijndaelAES.java +++ /dev/null @@ -1,1099 +0,0 @@ -// This implementation is a straight C-to-Java port of the -// public domain code from the original Rijndael authors: -// http://web.cs.ucdavis.edu/~rogaway/ocb/ocb-ref/ -// The original license declaration follows (all modifications -// are released under the same terms): - -/* - * rijndael-alg-fst.c - * - * @version 3.0 (December 2000) - * - * Optimised ANSI C code for the Rijndael cipher (now AES) - * - * @author Vincent Rijmen - * @author Antoon Bosselaers - * @author Paulo Barreto - * - * This code is hereby placed in the public domain. - * - * THIS SOFTWARE IS PROVIDED BY THE AUTHORS ''AS IS'' AND ANY EXPRESS - * OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED - * WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE - * ARE DISCLAIMED.
