Question 1

Is this encryption secure enough?

Accepted Answer

No. This tool implements classic substitution ciphers like Caesar, ROT13, Atbash, and Vigenère, only for learning, fun, or light obfuscation, and is easily broken. For truly secure encryption, use modern algorithm tools like AES.

Question 2

Which cipher algorithms are supported?

Accepted Answer

Four ciphers are supported: Caesar cipher (shifts by a specified amount), ROT13 (shift by 13, encoding and decoding are the same), Atbash (mirrors the alphabet), Vigenère cipher (shifts by each character of an alphabetic key). Only A–Z letters are transformed; numbers, punctuation, and other characters remain unchanged.

Question 3

How can encryption and decryption be reversed?

Accepted Answer

For Caesar and Vigenère, use the same shift amount or key and switch to 'Decrypt' to reverse; ROT13 and Atbash are self-inverting algorithms, so applying the same operation to the ciphertext yields the plaintext.
