Dynamic Parameter Shift Encryption (DPSE)

This project implements a novel encryption method called Dynamic Parameter Shift Encryption (DPSE), inspired by the classic Caesar Cipher but significantly enhanced with multiple dynamic parameters to increase complexity and security.

Overview

DPSE utilizes three dynamic parameters that shift and transform characters based on their position within the message. This multi-parameter approach ensures that each character's encryption is unique, making it more robust than traditional single-parameter ciphers.

Features

• Dynamic Zero Index (Karakter Index 0): A variable starting point for character mapping, which can be a single character for the entire message or a sequence of characters applied cyclically.
• Dynamic Shift Value (Bilangan Shift P): A variable integer value that determines the magnitude of the shift for each character. This can also be a single value or a sequence of integers.
• Dynamic Operator Pattern (Pola Operator r): A sequence of '+' or '-' operators that dictate whether the shift is an addition or subtraction, applied cyclically.
• Comprehensive Character Set: Supports encryption and decryption of alphanumeric characters (0-9, A-Z, a-z).
• Complexity Analysis: The encryption interface provides a real-time analysis of the encryption's complexity and security rating based on the parameters used.
• Step-by-Step Calculation Details: Both encryption and decryption processes offer detailed breakdowns of how each character is transformed, aiding in understanding and verification.

How it Works

Encryption (Encryption.html)

1. Input Message: The original text to be encrypted.
2. Parameter Configuration: Users input the Zero Index, Shift Value (P), and Operator Pattern (r). These can be single values or comma-separated sequences.
3. Character Processing: Each character in the message that is part of the defined sequence (0-9, A-Z, a-z) is processed individually.
   • The zeroChar (from Zero Index), integer (from Shift Value), and operator (from Operator Pattern) are applied cyclically based on the character's position.
   • The character's relative position to its zeroChar is calculated.
   • A zeroInfluence (quadratic based on zeroChar's position) is applied.
   • The shift operation (addition or subtraction) is performed using the integer and operator.
   • The final encrypted character is derived.
4. Output: The encrypted message and a detailed calculation log for each character.

Decryption (Decryption.html)

1. Input Encrypted Message and Parameters: To decrypt, the exact encrypted message and the original Zero Index, Shift Value, and Operator Pattern used during encryption are required.
2. Reverse Character Processing: For each encrypted character:
   • The zeroChar, integer, and operator are applied cyclically, mirroring the encryption process.
   • The zeroInfluence is removed.
   • The shift operation is reversed (e.g., if '+' was used for encryption, '-' is used for decryption).
   • The original character is recovered.
3. Output: The decrypted original message and a step-by-step explanation of the decryption process.

Usage

To use the DPSE calculator:

1. Open Encryption.html in your web browser to encrypt messages.
2. Open Decryption.html in your web browser to decrypt messages. Ensure you have the correct encryption parameters (Zero Index, Shift Value, Operator Pattern) used during encryption.

Development

The project is built using HTML, CSS, and JavaScript, making it a client-side application. No backend server is required.
