Treap API - Security Module

The Treap module within the Security subsystem provides advanced cryptographic operations and utilities for securing network communications.

Overview

Treaps are a type of randomized binary search tree that combines the properties of binary search trees and heaps. In the context of network security, treaps are leveraged for efficient and secure data management, key distribution, and intrusion detection. This module offers a robust set of functions for encrypting, decrypting, signing, and verifying data using treap-based algorithms.

privateKey PrivateKey Your private key. Yes
publicKey PublicKey The other party's public key. Yes

Returns:

The derived shared secret key.

Data Types

  • Bytes: Represents raw byte data.
  • KeyAlgorithm: String specifying key generation algorithm (e.g., 'RSA', 'ECC').
  • EncryptAlgorithm: String specifying encryption algorithm (e.g., 'AES-GCM', 'RSA-OAEP').
  • SignAlgorithm: String specifying signing algorithm (e.g., 'RSASSA-PKCS1-v1_5', 'ECDSA').
  • KeyExchangeAlgorithm: String specifying key exchange algorithm (e.g., 'ECDH').
  • PublicKey: Represents a public cryptographic key.
  • PrivateKey: Represents a private cryptographic key.
  • KeyPair: An object containing both publicKey and privateKey.
  • Signature: Represents a digital signature.
  • SecretKey: Represents a shared secret key.

Configuration Options

The SecurityConfig object can include parameters such as:

  • defaultAlgorithm: Specifies the default cryptographic algorithm to use.
  • keyStoragePath: Path for storing encrypted private keys.
  • hashingAlgorithm: Default hashing algorithm for integrity checks.
Note: Always handle private keys with extreme care. Do not expose them unnecessarily. Consider using hardware security modules (HSMs) for production environments.
Tip: For optimal security, use modern, robust algorithms like ECDSA for signing and AES-GCM for encryption.
Warning: Using deprecated or weak cryptographic algorithms can expose your system to security vulnerabilities. Always consult the latest security best practices.

Example Usage

Here's a basic example demonstrating encryption and decryption:

const security = new TreapSecurityContext(); // Generate a key pair for RSA encryption const keyPair = security.generateKeyPair('RSA'); const publicKey = keyPair.publicKey; const privateKey = keyPair.privateKey; const originalData = new Uint8Array([10, 20, 30, 40, 50]); try { // Encrypt data const encryptedData = security.encrypt(originalData, publicKey, 'RSA-OAEP'); console.log('Encrypted data:', encryptedData); // Decrypt data const decryptedData = security.decrypt(encryptedData, privateKey, 'RSA-OAEP'); console.log('Decrypted data:', decryptedData); // Verify that original and decrypted data match if (decryptedData.every((val, index) => val === originalData[index])) { console.log('Encryption and decryption successful!'); } else { console.error('Data mismatch after decryption!'); } } catch (error) { console.error('An error occurred:', error); }

Security Best Practices

When working with the Treap Security module:

  • Use strong, modern cryptographic algorithms.
  • Securely manage your private keys.
  • Always validate signatures to ensure data authenticity.
  • Implement proper error handling and logging for cryptographic operations.
  • Keep your libraries and dependencies updated to patch any security vulnerabilities.
