All Message Encryption Methods

— Shift, Shuffle, Simple Password, Multi-Shift & DES AES —

Look Like

* Only DES/AES enable selection of KeyStore keys.

Each method makes keys differently. We'll go from simple to complex.

Shift, Shuffle & Password all have a table…

…that maps clear letters → encrypted letters (A→ B; B→ C …)

Encrypt looks up the letter substitution from the table. Decrypt does it in reverse.

The

button makes different tables for each method

Shift

 =

C — because it's all you need to fill in encrypted alphabet

or

2 — because each clear letter is advanced 2 places; A→C, B→D, C→E…

Each click shifts or advances or rotates each encrypted letter one place.

Shuffle

 =

F, A, M, P… is the letter sequence of the encrypted alphabet

or

5, 25, 10, 12…  because A+5 is F, B+25 is A, C+10 is M,….

Each click creates new random encrypted letter mapping.

But since both are too hard to remember, use Simple Password ↓

Simple Password

If you type MYPASSWORD, since each letter (ie 'S') is only used once—

 =

M, Y, P, A, S, W, O, R, D + unused letters (B C E F G …...).

or

12, 23, 13, 23, 14, 17, 8, 10, 21, 18, 18, …  (see Shuffle)

Multi-Shift

If you type MYPASSWORD, every letter is used ('contrast with Simple Password' above)

 =

M, Y, P, A, S, S, W, O, R, D

        or

12, 24, 15, 0, 18, 18, 14, 17, 3
