FAQ
Questions people ask
Are classical ciphers secure?
No. Caesar, ROT13, Vigenere, and simple XOR are not appropriate for protecting sensitive information.
What are these ciphers useful for?
They are useful for learning cryptography basics, puzzles, demos, and reversible text transformations.
Which modern tool should I use for sensitive data?
Use AES for symmetric encryption or RSA for short messages and key exchange workflows.
