Description
Sub Cipher is an easy-to-use Encoder/Decoder app, which can encode or decode "simple substitution ciphers."
It works on the "Caesar" and "Atbash" style cipher methods, which are simple offset-alphabet ciphers. The well-known "Rot13" cipher is one of these.
Simply type or copy-paste your encoded or decoded text to and from e-mail, messages, social media, and it is immediately converted for you. Up to 2,000 characters can be converted at a time.
You can also capture the settings you have dialed in (as lines of text) to save in another document. This can be useful if you are publishing a newsletter or book of ciphers, and want to keep the settings you used with each cipher along with the cipher itself.
Here are the main features:
*Easy to use. Type into the plain-text or the cypher-text box, and the converted text is immediately displayed.
*Easy to transfer. You can select all the converted text and paste it into any other text document.
*Easy to adjust. Any substitution offset, forward or reverse can be dialed in.
*Easy to save. The settings you dial in can also be saved as text for your notes.
Caveat Emptor: These ancient styles of ciphers are very simple and easy to decode! This is simply a fun educational utility, and is not intended for serious "secret message" work.
What’s New
Version 1.0.5
Added new "Copy Text" buttons for easily copying encoded/decoded text to the clipboard.
Ratings and Reviews
Great piece of software
Mainly a simple substitution, but fun to use. There’s so many ciphers out there, I’d like to see a few more. Good job!
Great Software
Sub Cipher is a great software. It is so easy to use and works without flaws. You can type in your regular words or phrases and it automatically encrypts them according to the adjustable offset. You can make the offset either forward or reverse. This makes it so easy to create educational books. You can copy the plain text that you have inputted and then copy the automatically ciphered text and paste it in a slide presentation or book. This software works flawlessly and has such a well thought out aesthetically pleasing User Interface.
