EonaCat.Security 1.0.6

EonaCat Security

EonaCat Security library

The library provides:

A secrets manager.

• Securely load key/values from a file (or memory)
• Securely save key/values to a file (or memory)

AntiDebug features:

Call this at the entry point of your application (e.g., Main() or during startup):

AntiDebuggerModule.Start();

This will initialize the AntiDebugger module and start monitoring for debugging attempts.

To stop the AntiDebugger module, you can call:

AntiDebuggerModule.Stop();

If you want to manually trigger a crash (e.g., to confuse reverse engineers):

AntiDebuggerModule.Crash();

What It Detects:

• Debugging tools (e.g., dnSpy, x64dbg, windbg, ollydbg)
• Network monitors (e.g., Fiddler, Wireshark, Proxifier)
• Disassemblers/decompilers (e.g., IDA64, ILSpy, dotPeek)
• Other reverse engineering utilities.

AntiDumpModule The AntiDumpModule is a .NET anti-reverse-engineering component that attempts to corrupt the PE (Portable Executable) headers and section table of the currently running process. This makes it harder for tools like dumpers and decompilers to generate a valid copy of the executable

How to use:

AntiDumpModule.Start();

This will initialize the AntiDump module and start monitoring for dumping attempts.

To stop the AntiDump module, you can call:

AntiDumpModule.Stop();

Bytes Generator:

How to use:

// Generate random bytes
byte[] randomBytes = BytesGenerator.RandomBytes(16);

// Derive bytes from a password
string password = "securepassword";
byte[] salt = BytesGenerator.RandomBytes(8);
byte[] derivedBytes = BytesGenerator.BytesFromPassword(password, salt, 16);

// Convert bytes to string
string hexString = BytesGenerator.BytesToString(randomBytes);

// Convert string to bytes
byte[] bytesFromHex = BytesGenerator.StringToBytes(hexString);

Data Compressor:

How to use:

// Compress data
byte[] data = System.Text.Encoding.UTF8.GetBytes("This is some data to compress");
byte[] compressedData = DataCompressor.Compress(data);

// Decompress data
byte[] decompressedData = DataCompressor.Decompress(compressedData);
string decompressedString = System.Text.Encoding.UTF8.GetString(decompressedData);

DataEncryptor:

How to use:

// Encrypt an object
string originalData = "Sensitive data";
byte[] key = BytesGenerator.RandomBytes(32); // AES-256 key
byte[] iv = BytesGenerator.RandomBytes(16);  // AES IV
byte[] encryptedData = DataEncryptor.Encrypt(originalData, key, iv);

// Decrypt the object
string decryptedData = DataEncryptor.Decrypt<string>(encryptedData, key, iv);

FileEncryptor:

How to use:

// Encrypt a file
string inputFilePath = "file.txt";
string outputFilePath = "encryptedFile.xxx";
byte[] key = BytesGenerator.RandomBytes(32); // AES-256 key
byte[] iv = BytesGenerator.RandomBytes(16);  // AES IV
FileEncryptor.Encrypt(inputFilePath, outputFilePath, key, iv);

// Decrypt a file
string decryptedFilePath = "decryptedFile.txt";
FileEncryptor.Decrypt(outputFilePath, decryptedFilePath, key, iv);

Hash computation:

How to use:

// Compute hash
byte[] data = System.Text.Encoding.UTF8.GetBytes("This is my data");
byte[] hash = HashComputer.Compute(data);

// Verify hash
bool isMatch = HashComputer.Verify(data, hash);
