Emu's Encryption Tool For Mac

Emu's Encryption Tool is a free and open source tool that encrypts text using polyalphabetic methods.

Because there are no mathematical functions or formulas the encrypted texts can't be cracked using bruteforce attacks or  other password cracking methods used in IT security.

The texts are encrypted with random codes and fixed passwords but can also be used as an One-Time-Pad (OTP) which uses extreme long random passwords and codes and is impossible to encrypt.

· For using Emu's Encryption Tool you first need a sender and a receiver. Both need the same codetable, so one of them should create one using the "Random" option right below the codetable and save it to a file.

· All senders and receivers need to have the same codetable! You don't need to change the codetable very often so you can keep the codefile and use it for every encryption.

· When this step is done the sender has to set up a password and can type any text in the area upper left. With a click on"Encrypt" the encrypted text appears in the lower text area.

· This text can now be sent to all receivers. Of course they need to know the password too. The password should be changed quite often because its the key to decrypt the text. It's not necessary to change it with every encryption. A good way is to use one password a day.

· When the receivers get the encrypted text, they just have to paste it in the text area on the lower left, type in the password, choose the right codetable and press "decrypt". The decrypted text appears in the text area on the upper left. That's it.
