MonoCipher 0.1.3

A package for monoalphabetic ciphers (message encryption and decryption).

MonoCipher

MonoCipher is python programmed package which allow users to encrypt and decrypt messages in three different levels

1. Simple Cryption with Shift number
2. Byte Cryption with an advance method of encryption and decryption with Initialization Vector (IV) and Cipher Text. more on IV
3. Salt Cryption with advance method of encryption and decryption with Initialization Vector (IV), Cipher Text, Password and salt. more on salt

The core module used in the project is pycryptodome

To Use This Module

pip install MonoCipher

Features

Simple Encryption

• This function encrypts decrypts message using shift method
• This function takes an input of message and shift number | shift_encrypt(message, shift)
  For Decrypting the message the function takes as same | shift_encrypt(message, shift)

Byte Encryption

• This encryption works in an advance method of encryption and decryption with Initialization Vector (IV) and Cipher Text. more on IV
• This function takes an input of Message and Password and returns VI and Cipher Text | byte_encrypt(message, password)
• For Decrypting the message the function takes VI, Cipher Text, and Password | byte_decrypt(iv, ciphertext, password)

Salt Encryption

• This encryption works in an advance method of encryption and decryption with Initialization Vector (IV), Cipher Text, Password and salt. more on salt
• This function takes an input of Message and Password and returns Salt, VI and Cipher Text | salt_encrypt(message, password)
  For Decrypting the message the function takes Salt, VI, Cipher Text, and Password | salt_decrypt(salt, iv, ciphertext, password)
• On this process the encrypt function generates a 256-bit key | generate_key(password, salt)

Certainly! Here's the updated usage section for the README.md file:

Usage

Simple Encryption Module:

shift_encrypt:

Encrypts a message using a simple Caesar cipher with a specified shift value.

from MonoCipher.SimpleEncryption import shift_encrypt

message = "Hello, World!"
shift = 3

encrypted_message = shift_encrypt(message, shift)
print("Encrypted message:", encrypted_message)

shift_decrypt:

Decrypts a message encrypted with a Caesar cipher using the same shift value.

from MonoCipher.SimpleEncryption import shift_decrypt

encrypted_message = "Khoor, Zruog!"
shift = 3

decrypted_message = shift_decrypt(encrypted_message, shift)
print("Decrypted message:", decrypted_message)

Byte Encryption Module:

byte_encrypt:

Encrypts a message using AES encryption in CBC mode with a provided key.

from MonoCipher.ByteEncryption import byte_encrypt

message = "Hello, World!"
password = "MySecretPassword"

iv, ciphertext = byte_encrypt(message, password)
print("IV:", iv)
print("Ciphertext:", ciphertext)

byte_decrypt:

Decrypts a message encrypted with AES encryption using the same key and initialization vector (IV).

from MonoCipher.ByteEncryption import byte_decrypt
  
iv = "some_base64_encoded_iv"
ciphertext = "some_base64_encoded_ciphertext"
password = "MySecretPassword"

decrypted_message = byte_decrypt(iv, ciphertext, password)
print("Decrypted message:", decrypted_message)

Salt Encryption Module:

salt_encrypt:

Encrypts a message using AES encryption in CBC mode with a provided password and a random salt.

from MonoCipher.SaltEncryption import salt_encrypt

message = "Hello, World!"
password = "MySecretPassword"

salt, iv, ciphertext = salt_encrypt(message, password)
print("Salt:", salt)
print("IV:", iv)
print("Ciphertext:", ciphertext)

salt_decrypt:

Decrypts a message encrypted with AES encryption using the same password and salt.

from MonoCipher.SaltEncryption import salt_decrypt

salt = "some_base64_encoded_salt"
iv = "some_base64_encoded_iv"
ciphertext = "some_base64_encoded_ciphertext"
password = "MySecretPassword"

decrypted_message = salt_decrypt(salt, iv, ciphertext, password)
print("Decrypted message:", decrypted_message)

HMAC Encryption Module:

hmac_encrypt:

Encrypts a message using HMAC authentication.

from MonoCipher.HmacEncryption import hmac_encrypt

message = "Hello, World!"
password = "MySecretPassword"

salt, nonce, ciphertext, tag = hmac_encrypt(message, password)
print("Salt:", salt)
print("Nonce:", nonce)
print("Ciphertext:", ciphertext)
print("Tag:", tag)

hmac_decrypt:

Decrypts a message encrypted with HMAC authentication using the same parameters.

from MonoCipher.HmacEncryption import hmac_decrypt

salt = "some_base64_encoded_salt"
nonce = "some_base64_encoded_nonce"
ciphertext = "some_base64_encoded_ciphertext"
tag = "some_base64_encoded_tag"
password = "MySecretPassword"

decrypted_message = hmac_decrypt(salt, nonce, ciphertext, tag, password)
print("Decrypted message:", decrypted_message)

Nonce Encryption Module:

nonce_encrypt:

Encrypts a message using a nonce for authentication.

from MonoCipher.NonceEncryption import nonce_encrypt

message = "Hello, World!"
password = "MySecretPassword"

salt, nonce, ciphertext, tag = nonce_encrypt(message, password)
print("Salt:", salt)
print("Nonce:", nonce)
print("Ciphertext:", ciphertext)
print("Tag:", tag)

nonce_decrypt:

Decrypts a message encrypted with a nonce for authentication using the same parameters.

from MonoCipher.NonceEncryption import nonce_decrypt

salt = "some_base64_encoded_salt"
nonce = "some_base64_encoded_nonce"
ciphertext = "some_base64_encoded_ciphertext"
tag = "some_base64_encoded_tag"
password = "MySecretPassword"

decrypted_message = nonce_decrypt(salt, nonce, ciphertext, tag, password)
print("Decrypted message:", decrypted_message)

MAC Encryption Module:

mac_encrypt:

Encrypts a message using AES-GCM with a provided password.

from MonoCipher.MacEncryption import mac_encrypt

message = "Hello, World!"
password = "MySecretPassword"

salt, nonce, ciphertext, tag = mac_encrypt(message, password)
print("Salt:", salt)
print("Nonce:", nonce)
print("Ciphertext:", ciphertext)
print("Tag:", tag)

mac_decrypt:

Decrypts a message encrypted with AES-GCM using the same parameters.

from MonoCipher.MacEncryption import mac_decrypt

salt = "some_base64_encoded_salt"
nonce = "some_base64_encoded_nonce"
ciphertext = "some_base64_encoded_ciphertext"
tag = "some_base64_encoded_tag"
password = "MySecretPassword"

decrypted_message = mac_decrypt(salt, nonce, ciphertext, tag, password)
print("Decrypted message:", decrypted_message)

These are the usages for each of the six functions provided by the encryption modules. You can customize the input values such as the message, shift value, password, IV, and ciphertext according to your requirements.
