simple_aes_cbc

This is a TypeScript module that provides a simple class for encryption and decryption functionality. It uses the AES-CBC-algorithm and depends on the global crypto, atob and btoa functions to perform the encryption and decryption, so it can be used in deno >= 1.15 and node >= 16.0.0 .

Installation

deno

import { SimpleAesCbc } from "https://deno.land/x/simple_aes_cbc/mod.ts";

node

npm install simple-aes-cbc
bun install simple-aes-cbc
yarn install simple-aes-cbc

... etc

Usage

Here's an example of how to use this module:

deno

import { SimpleAesCbc } from "https://deno.land/x/simple_aes_cbc/mod.ts";

const stringCrypto = new SimpleAesCbc("1234567890123456", crypto.subtle);

const data = "hello my friend";

const encrypted = await stringCrypto.encryptString(data);

const decrypted = await stringCrypto.decryptString(encrypted);

console.log(decrypted); // "hello my friend"

node

import { webcrypto } from "node:crypto";
import { SimpleAesCbc } from "simple-aes-cbc";

const stringCrypto = new SimpleAesCbc("1234567890123456", webcrypto.subtle);

const data = "hello my friend";

const encrypted = await stringCrypto.encryptString(data);

const decrypted = await stringCrypto.decryptString(encrypted);

console.log(decrypted); // "hello my friend"

API

new SimpleAesCbc(privateKey: string, subtleCrypto: SubtleCrypto)

This is the constructor of the SimpleAesCbc class. It takes a privateKey and a subtleCrypto as a parameter, which is used to encrypt and decrypt the data.

encrypt(data: BufferSource): Promise<ArrayBuffer>

This method encrypts the given data.

decrypt(data: BufferSource): Promise<ArrayBuffer>

This method decrypts the given data.

encryptString(data: string): Promise<string>

This will encrypt the given string and wrap transform it to base64.

decryptString(data: string): Promise<string>

This will decrypt the given base64 string and transform it to a normal string.
