Sub Cipher is an easy-to-use Encoder/Decoder app, which can encode or decode your text using various "simple substitution" cipher methods. * 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. Sub Cipher offers you the encoded text, placeholder-text, and even a magic decoder wheel that you can add to your own books and publications. You can also capture the cipher 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 a record of the settings you used with each cipher along with the cipher itself. 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. *Easy to publish: Any ciphers you make are 100% yours to publish and sell; no copyright restrictions or restrictive "commercial use" clauses here. *Forever Free: Download this software once and it is yours forever. You get all future new features and updates free. No upgrade costs or "subscription/rental" fees. Ever. *No Ads: You are never distracted from enjoying my software. *Human-Made: This software was completely and carefully hand-designed and written by me. No A.I. toys were allowed anywhere near this software. *Private: Your work is safely yours and always stays on your computer. You are never required to create internet accounts, and none of your information is ever stored in the cloud. * Caveat Emptor: It uses the "Caesar" and "Atbash" style cipher methods, which are simple offset-alphabet ciphers. The well-known "Rot13" cipher is one of these. 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.
