CipherFlow System is a console application written in C that allows file encryption, decryption, and task scheduling.
The system is based on a custom algorithm using a password, combined with a dynamic versioning mechanism and a non-linear permutation process.
- 🔒 File Encryption Encrypts one or multiple files using a password and a version, with internal data permutation.
- 🔓 File Decryption Decrypts encrypted files using the correct password and version.
- ⏳ Scheduled Encryption Allows scheduling file encryption at a specific date and time.
- ⏳ Scheduled Decryption Allows scheduling file decryption at a specific date and time.
- 🌐 Multilingual Support Dynamic language switching (French / English)
- 🛡️ Safety Protection Prevents accidental file overwriting or deletion.
- Dynamic handling of multiple files with secure memory allocation
- Input validation (password, version, file paths)
- Scheduling system based on system date and time
- Password strength estimation based on character repetition
- Dual-language display (EN / FR)
The system relies on a custom algorithm composed of several steps:
- Key generation from password and version
- Data transformation based on the generated key
- Non-linear permutation using version-adjusted key values
- Progressive text rendering
- Color effects and “Matrix-style” animations
- Windows alerts using MessageBox()
This project helps practice:
- File handling in C (fopen, fclose, getc, fprintf)
- Dynamic memory management (malloc, calloc, free)
- Use of struct for data organization
- Console UI + Windows popups integration
- Language: C
- Compiler: GCC or any standard C compiler.
gcc main.c function.c -o FILE_CRYPTER.exe -luser32
Bash
./FILE_CRYPTER.exe
1️⃣ Personal Data Protection
- Secure sensitive files (passwords, private documents, confidential data)
- Encrypt data before storage or sharing
2️⃣ Security Automation
- Schedule encryption/decryption tasks
- Reduce manual intervention
3️⃣ Data Loss & Leak Prevention
- Protect files from unauthorized access
- Secure files before transfer
All file types supported by file reading functions.
- Works on Windows only
- Correct password and version are required for decryption
- Scheduled encryption works even if the file does not exist yet
- Graphical User Interface (GUI)
- Logging and monitoring system
