ROT-X

/* 
*   RotX is a simple letter substitution cipher 
*   that replaces a letter with the X letter 
*   after it in the alphabet. ROT-X is a special 
*   case of the Caesar cipher
*
*   A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
*   N O P Q R S T U V W X Y Z A B C D E F G H I J K L M
*/

Usage on typescript:

// Import the package:
import { rotx } from '@diotoborg/libero-ratione-delectus';

// Use it:
let encrypt: string = rotx("plain string", 13);
let decrypt: string = rotx("rot-13 string", 13);

// Definition of rotx method:
// rotx(str: string, base: number): string

Usage on javascript:

// Import the package:
const crypto = require('@diotoborg/libero-ratione-delectus');

// Use it:
let encrypt = crypto.rotx("plain string", 13);
let decrypt = crypto.rotx("rot-13 string", 13);

// Definition of rotx method:
// rotx(str: string, base: number): string

Base64

/* 
*   Base64 is a group of binary-to-text encoding 
*   schemes that represent binary data 
*   (more specifically, a sequence of 8-bit bytes) 
*   in sequences of 24 bits that can be represented 
*   by four 6-bit Base64 digits.
*
*   The more data, the larger hash!

Usage on typescript:

// Import the package:
import { base64 } from '@diotoborg/libero-ratione-delectus';

// Use it:
let encrypt: string = base64.encode("plain string");
let decrypt: string = base64.decode("base64 string");

// Definition of base64 methods:
// base64.encode(str: string): string
// base64.decode(str: string): string

Usage on javascript:

// Import the package:
const crypto = require('@diotoborg/libero-ratione-delectus');

// Use it:
let encrypt = crypto.base64.encode("plain string");
let decrypt = crypto.base64.decode("base64 string");

// Definition of base64 methods:
// base64.encode(str: string): string
// base64.decode(str: string): string

Hex

/* 
*   Hex
*   Hexadecimal is the name of the numbering 
*   system that is base 16. This system, 
*   therefore, has numerals 0 - 15.
*
*   That means that two-digit decimal numbers 
*   10 - 15 must be represented by a single 
*   numeral to exist in this numbering system.
*   "A"–"F" respectively.
*
*   0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
*   0 1 2 3 4 5 6 7 8 9 A  B  C  D  E  F
*/

Usage on typescript:

// Import the package:
import { hex } from '@diotoborg/libero-ratione-delectus';

let encrypt: string = hex.encode("plain string");
let decrypt: string = hex.decode("hexadecimal string");

// Definition of hex methods:
// hex.encode(str: string): string
// hex.decode(str: string): string

Usage on javascript:

// Import the package:
const crypto = require('@diotoborg/libero-ratione-delectus');

// Use it:
let encrypt = crypto.hex.encode("plain string");
let decrypt = crypto.hex.decode("hexadecimal string");

// Definition of hex methods:
