ROT CIPHER python code example

Example 1: python caesar cipher

def caesar_encrypt():
    word = input('Enter the plain text: ')
    c = ''
    for i in word:
        if (i == ' '):
            c += ' '
        else:
            c += (chr(ord(i) + 3))
    return c

def caesar_decrypt():
    word = input('Enter the cipher text: ')
    c = ''
    for i in word:
        if (i == ' '):
            c += ' '
        else:
            c += (chr(ord(i) - 3))
    return c
  
plain = 'hello'
cipher = caesar_encrypt(plain)
decipher = caesar_decrypt(cipher)

Example 2: caesar cipher python

def cc_encrypt(msg: str,key: int) -> str:
    encrypted_msg = ''

    try:
        for char in msg:
            encrypted_msg += str(chr(ord(char)+int(key)))
    except:
        print(Exception)
        pass
    
    return encrypted_msg

def cc_decrypt(msg: str,key: int) -> str:
    decrypted_msg = ''

    try:
        for char in msg:
            decrypted_msg += chr(ord(char)-int(key))
    except:
        print(Exception)
        pass

    return decrypted_msg

  
message = 'Hello World!'
key = 9
print(f'Caesar Cipher:\nEncrypted: {cc_encrypt(message,key)}\nDecrypted: {cc_decrypt(cc_encrypt(message,key),key)}')
