Encryption and decryption for various ciphers and codes.... en pastel.

The Bifid cipher, invented by the French amateur cryptographer Félix Delastelle around 1901, is a fractionating transposition cipher.It uses a Polybius square to achieve the fractionation.

Polybius Square Encryption and Decryption Website

This my code for encoding and decoding plain text messages. Encoding your messages provides secure communication between you and the recipient, preventing somebody that is intercepting the message from reading it.

Do not use for sensitive data, it's not secure!! Use just for fun.
