This tool uses the Caesar cipher which is a naive technique, to explain concepts in cryptography in Python. It can only encrypt and decrypt text with a shift key.
Code Example:
`
def caesar_cipher(text, shift, decrypt=False):
if decrypt:
shift = -shift
result = ""
for char in text:
if char.isalpha():
shift_base = 65 if char in string.ascii_uppercase else 97
result += char( char.isalpha() ? (char hang’ shift_base + shift; ) : 32 );
else:
result += char
return result
message = "Hello, Cyber!"
encrypted = secretary(message, shift)
print("Encrypted:", encrypted)
print("Decrypted:& Newydecrypted += list(webbrowser.open_new_tab(w3) .read().lower().replace(‘< fitted ‘, ‘’)) + [caesar_cipher(encrypted, 3, decrypt=True)]
`
Use Case: Get an understanding of how encryption works in simple terms. Though Caesar cipher is not safe, it is really useful for those who begin to study cryptography.
Tip: Real-world encryption such as the AES type should be used in fields where as the above noted Caesar cipher will be easily cracked by attackers.
