🛡️ Encryption & Decryption Tools

Encrypt and decrypt your data using industry-standard algorithms

AES-256

Advanced Encryption Standard - The gold standard for symmetric encryption

DES

Data Encryption Standard - Legacy 56-bit encryption

⚠️ DES is considered insecure for modern applications. Use AES for new projects.
RSA-2048

Rivest-Shamir-Adleman - Asymmetric encryption with public/private keys

🎲 Password Generator

Generate secure random passwords

-

🔑 Key Generator

Generate cryptographic keys

#️⃣ Hash Functions

Calculate cryptographic hashes of text or files

🔮 Post-Quantum Cryptography

Quantum-resistant algorithms to protect against future quantum computer attacks

⚠️
Why Post-Quantum?

Quantum computers could break RSA, ECC, and DH within hours. Post-quantum algorithms are designed to resist both classical and quantum attacks.

CRYSTALS-Kyber

NIST Post-Quantum Standard - Key Encapsulation Mechanism (KEM)

NIST Approved Security Level 3 (192-bit quantum security)

🔐 Key Encapsulation

CRYSTALS-Dilithium

NIST Post-Quantum Standard - Digital Signature Algorithm

NIST Approved Security Level 3

✍️ Digital Signatures

Learning With Errors (LWE)

Mathematical foundation for Kyber and Dilithium

2D Lattice Visualization

⚛️ Quantum Cryptography

Leverage quantum mechanics for unbreakable encryption

⚛️

Quantum cryptography uses the laws of physics (quantum mechanics) to guarantee security. Any eavesdropping attempt disturbs the quantum states and can be detected.

BB84 Protocol

First quantum key distribution protocol (Bennett & Brassard, 1984)

🔐 Quantum Key Distribution Simulation

Quantum RNG

True random numbers from quantum phenomena

🎲 Randomness Tests

Quantum Entanglement

"Spooky action at a distance" - Einstein

↑ Particle A
⟷
↓ Particle B

Entangled particles have correlated properties regardless of distance

👁️ Visual Cryptography (Steganography)

Hide secret messages in images using LSB steganography

📁

How It Works

1. LSB Steganography

We use Least Significant Bit encoding to hide your message in the image pixels.

2. Invisible Changes

The modifications are imperceptible to human eyes while storing your secret data.

3. Secure Extraction

Only someone with the encoded image can extract the hidden message.

📚 Learn Cryptography

Understanding the fundamentals of cryptographic systems

🔐 What is Cryptography?

Cryptography is the practice and study of techniques for secure communication. It transforms readable data into unreadable format to protect it from unauthorized access.

  • Confidentiality - Keeping information private
  • Integrity - Ensuring data hasn't been modified
  • Authentication - Verifying identity
  • Non-repudiation - Proving who sent a message

🔮 Post-Quantum Cryptography

Quantum computers could break RSA, ECC, and DH. Post-quantum algorithms are designed to resist quantum attacks.

Algorithm Type Quantum Safe
RSA-2048 Encryption/Signature ❌ Broken by Shor's
ECC P-256 Encryption/Signature ❌ Broken by Shor's
