[FEATURE REQUEST] One-Time Pad Cipher #6941
Description
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.
