What Is the Vigenère & ROT47 Cipher Studio?
Encode and decode classical ciphers while preserving punctuation and letter case.
How It Works
Choose Vigenère or ROT47. Vigenère uses an A–Z keyword and a direction switch; applying ROT47 twice restores the original ASCII text.
When to Use It
Learning classical cryptography and solving puzzles. These ciphers are not suitable for protecting confidential information.
