• Encryption
  • Plaintext
  • Shift Number
  • Rail Number
• Decryption
  • Cipher Text
  • Shift Number
  • Rail Number
  • Alphabet

Output

Output can be displayed on the terminal or written to a file

Encryption Program

Separate Program Dedicated to Encrypting the Plaintext - enc_section_cipher.py

• Includes a Step by Step view of the Encryption
• Does not support input from a file or output to a file

Decryption Program

Separate Program Dedicated to Decrypting the Cipher Text - dec_section_cipher.py

• Includes a Step by Step view of the Decryption
• Does not support input from a file or output to a file
