====================
ShortCrypt is a very simple encryption library, which aims to encrypt any data into something random at first glance. Even if these data are similar, the ciphers are still pretty different. The most important thing is that a cipher is only 4 bits larger than its plaintext so that it is suitable for data used in an URL or a QR Code. Besides these, it is also an ideal candidate for serial number generation.
``typescript`
import { ShortCrypt } from "short-crypt";
Then, create a ShortCrypt instance with a key (string).
`javascript`
const sc = new ShortCrypt(key);
For encryption, you can choose to use one of these following methods:
* encrypt: encrypts data to an object, a cipher separated into base and bodyencryptToURLComponent
* : encrypts data to a string suitably concatenated with URLsencryptToQRCodeAlphanumeric
* : encrypts data to a string with the compatibility with QR code alphanumeric mode
Only a string or a byte array can be encrypted.
`javascript`
const cipher1 = sc.encryptToURLComponent(plainText);
const cipher2 = sc.encryptToQRCodeAlphanumeric(plainText);
For decryption, you can use decrypt, decryptURLComponent, or decryptQRCodeAlphanumeric method.
`javascript``
const result1 = sc.decryptURLComponent(cipher1);
const result2 = sc.decryptQRCodeAlphanumeric(cipher2);
