An app that can be used to create encrypted text with Caesar or to find the original text of an encrypted text.
The text that can be encrypted is English, Korean, and numbers.

Caesar cipher:
Shift an alphabet by a certain distance to replace it with another alphabet
Ex) A 1→ B
A 3→ D
NICE 2→ PKEG

Easy to use
After selecting the language, enter text and set the distance to push the letters.

Find the original text of English text encrypted with Caesar:
If you use this function after inputting English text encrypted with Caesar, the text is output with all the number of cases of the extruded distance applied.
Find meaningful text in the output text list. (English Decryption button)

Hangul Caesar Support
The Caesar cipher, which was used in English, was also applied to Korean.
The difference with English Caesar can be applied separately for each consonant and vowel.

Examples of application of consonants:
each 1→ cut
Each 2 → pleasure

Collection example:
each 1→ passenger
Each 2→ 갹

Base application example:
each 1→ liver
each 2→ trapped

All at the same time Example:
each 1 → broken
Each 2→

Upgraded Caesar 2.0 Support
This is a self-made method with increased security from the existing Caesar method.
In the existing Caesar method, if you set the distance to be pushed, all letters are replaced only by the specified distance.

Ex) AAAAA 1→ BBBBB

However, in Caesar 2.0, you can specify a different distance to be pushed out for each letter, which increases security.
From 0 to 9, you can specify the distance to push each letter.
All you have to do is list the numbers in the order of the distances you want to assign to the letters.

Ex) AAAAA 12→ BCBCB

This pushes the first alphabet out by 1 and the second by 2.
Again, the third letter is pushed back by 1 and the fourth letter is repeated by 2.

Ex) AAAAA 123→ BCDBC
AAAAA 1234→ BCDEB

If you specify 4 numbers as in 1234 above, it has the same effect as giving a 4-digit password to the text.

Ex) TEST 7584 → AJAX
To figure out the original text of AJAX, TEST, you must know the password 7584.
