AES - file encryption

Requirements:

nodejs 15.0.0 or above
npm 7.0.2 or above

Install:

git clone https://github.com/rajamarko/learning-encryption-aes.git
cd learning-encryption-aes

npm install

Encrypt:

npm start e [filename.ex]

A new encrypted file will be created, in the same directory as the original file. '-encrypted' will be added before the file extension (filename-encrypted.ex).
Absolute path can be provided for filename.

Decrypt

npm start d [filename-encrypted.ex]

A new encrypted file will be created, in the same directory as the original file. '-decrypted' will be added before the file extension (filename-decrypted.ex).
Absolute path can be provided for filename.

Create new key

npm start -createKey

A new encryption key will be created. Also if a key is missing, it will be created on the next file encryption.

Description

On every encryption, a new initialization vector (iv) file is created, and the same initialization vector must be used for decrypting the file.
