Version: v1.2

A simple Python-based library that provides a wide variety of encoding and decoding (encryption/decryption) algorithms for basic string and integer transformations.

• ROT13 cipher
• String reversal
• Static binary (int ↔ binary)
• Binary encoding (str ↔ bin)
• Random case converter
• ASCII encoding/decoding
• Static octal & hex conversions
• Atbash cipher
• Caesar cipher (basic & unstable)
• Normal hex view (xxd-style)

Each feature is available for both encryption and decryption where applicable.

• Python 3.x

No external dependencies required.

Import or run the file directly to access the methods via:

from cryptographic_api import encrypt, decrypt

encrypt.rot13("hello") # Output: 'uryyb' decrypt.rot13("uryyb") # Output: 'hello' encrypt.static_binary(123) # Output: '1111011' decrypt.static_binary('1111011') # Output: 123 encrypt.reverse("ABC") # Output: 'CBA' decrypt.reverse("CBA") # Output: 'ABC' encrypt.ascii("hi") # Output: '104 105' decrypt.ascii("104 105") # Output: 'hi'

Run automated encoding/decoding tests:

tests.static_binary_encrypt() tests.static_binary_decrypt() tests.binary_encrypt() tests.binary_decrypt() tests.reverse_encrypt() tests.reverse_decrypt() tests.rot13_encrypt() tests.rot13_decrypt() tests.random_case_encrypt() tests.random_case_decrypt() tests.ascii_encrypt() tests.ascii_decrypt() tests.static_hex_encrypt() tests.static_hex_decrypt() tests.static_octal_encrypt() tests.static_octal_decrypt() tests.normal_hex_encrypt() tests.normal_hex_decrypt()

Each test prints input/output data for verification.

• Caesar cipher is unstable and should not be used in production.
• Random case transformation is non-reversible by design.
• Some converters only work with integer inputs; exceptions are raised otherwise.

No third-party libraries were used in the code; everything was done using algorithms. If there are any problems, write to issues
