C-LCRYPT: Unbreakable Binary-Level Encryption

=== Remake of LCRYPT on C++ | Gained +99.68% performance | All I/O operations runs on RAM now ===

In the digital age, securing data at its core is crucial. C-LCRYPT offers a revolutionary encryption solution that protects data at the binary level, ensuring integrity and confidentiality. Unauthorized access is impossible without the decryption keys.

Description

C-LCRYPT is a C++ encryption program that encrypts files at the binary level with RAM-based I/O. It features byte shuffling, binary reversal, bit insertion, byte substitution using a randomized table, and XOR key encryption. This method provides top-tier security, making data indecipherable without the correct keys and resisting reverse engineering. Even with the C-LCRYPT tool, brute force decryption is impractical due to the vast number of possible combinations and required computational resources, posing a significant barrier even against advancements in quantum computing.

Disclaimer: This tool does not leave any identifiable signature or trace that could be linked back to the tool or its author. The resulting encryption cannot be analyzed or reverse-engineered to understand the algorithm's nature without access to the program's source code.
