FlipPad Cipher

The FlipPad Cipher is a custom encryption method that combines a unique transformation process with a one-time pad (OTP) for enhanced security. This cipher is designed for educational and personal use and implements the following encryption steps:

1. Split the Word:

   • The input text is divided into two halves. For odd-length words, the extra character is assigned to the first half.

2. Reverse the Second Half:

   • The second half of the word is reversed to introduce a layer of obfuscation.

3. Apply the One-Time Pad:

   • A one-time pad is applied to both halves of the transformed text, ensuring strong encryption.

4. Recombine the Halves:

   • The processed halves are concatenated to form the final encrypted output.

Features

• Strong security through one-time pad encryption.
• Obfuscation via reversal of part of the input.
• Suitable for short, string-based encryption tasks.

How It Works

Encryption Example:

1. Input: cipher
2. Split: cip and her
3. Reverse second half: cip and reh
4. Apply OTP (key: [4, 5, 9, 3, 8, 2]):
   • First half: cip becomes how
   • Second half: reh becomes vmj
5. Recombine: howvmj
