Homophonic Cipher
Encrypt and decrypt text using a homophonic substitution cipher. Each letter maps to multiple numeric codes based on English letter frequency, making frequency analysis harder.
How to Use Homophonic Cipher
Select encrypt or decrypt mode, enter your text, and click the button. Encryption produces space-separated numeric codes; decryption converts codes back to letters.
