[KopyTKG]

v3.1.0 — 2025-06-30

Full Changelog: v3.0.0...v3.1.0

Notable Changes

• Added improved handling for writing and stripping padding on decryption, ensuring output files exactly match original sizes.
• Enhanced metadata struct: added/clarified version, mode, and IV fields for better future compatibility and file identification.
• Improved error reporting and panic handling for out-of-bounds slice accesses, especially during block conversion and file writing.
• Refactored the binary stream writing logic to be safer and more robust, avoiding panics when handling the last block of data.
• Added documentation and comments to clarify core sections relating to cryptographic block handling and file I/O.

Bug Fixes

• Fixed a runtime panic caused by attempting to slice blocks out of range when converting [4]uint32 to []byte.
• Corrected logic for writing only the necessary number of bytes on the last decrypted block, avoiding file size mismatches and padding leaks.
• Improved error messages and logging during encryption/decryption operations.

Internal/Developer

• Refactored internal APIs to use []uint32 and [4]uint32 more safely and idiomatically.
• Added more robust progress and UI update hooks.
