Advanced Multi-Layer Encryptor

An advanced, multi-layer encryptor designed for maximum security by combining XOR, AES, HMAC, and PBKDF2. This encryptor ensures data integrity, confidentiality, and resistance against common cryptographic attacks.

Features

• 🔒 Multi-layer encryption:
  • XOR Encryption: Adds an extra layer of obfuscation.
  • AES Encryption: Industry-standard symmetric encryption with a 256-bit key.
  • HMAC Verification: Ensures data authenticity and integrity.
  • PBKDF2 Key Derivation: Protects against brute-force attacks using a secure salt-based key generation.
• 🛡️ Salted encryption: Each encryption generates a unique salt for better security.
• ✅ Integrity protection: Validates encrypted data with HMAC.
• 🎲 Randomized Initialization Vectors (IVs): Ensures unique encryption for each operation.

How It Works

1. Key Derivation:
   • A password is processed with a randomly generated salt using PBKDF2 to produce a 256-bit cryptographic key.
2. Encryption Process:
   • The plaintext is first encrypted with XOR using a derived key.
   • The resulting data is further encrypted with AES.
   • An HMAC is calculated on the AES-encrypted data to verify its integrity.
3. Decryption Process:
   • Splits the encrypted data into salt, AES-encrypted payload, and HMAC.
   • Verifies the HMAC to ensure data integrity.
   • Decrypts the AES payload, followed by XOR decryption, to recover the original plaintext.

Usage

Encryption Example

string plaintext = "Sensitive Data";
string password = "SecurePassword123";

string encrypted = EncryptComplex(plaintext, password);
Console.WriteLine("Encrypted: " + encrypted);
