[FEATURE REQUEST] One-Time Pad Cipher

[Shewale41]

What would you like to Propose?

Title: Add One-Time Pad Cipher Implementation

---

🧠 Overview

The One-Time Pad (OTP) is an unbreakable cipher (if key truly random and used once). Implementing it helps demonstrate the concept of perfect secrecy in cryptography.

📂 Implementation Details

• Folder: src/main/java/com/thealgorithms/ciphers/
• Filename: OneTimePadCipher.java
• Approach:
  • Generate a random key same length as plaintext.
  • XOR plaintext with key for encryption.
  • Apply XOR again for decryption.

✅ Expected Deliverables

• Complete encrypt/decrypt implementation.
• Example with random key generation.
• Tests for multiple plaintext lengths.
• Comments explaining cryptographic limitations (key reuse).

🧑‍💻 Additional Notes

A simple yet powerful algorithm showing fundamentals of symmetric encryption and XOR logic.
