AES Keygen

The AES Keygen scripts demonstrates use of the EaaS API (https://www.qrypt.com/docs/eaas) to download Quantum Random, and convert that random to AES keys. It will output a CSV file, each row being a keys and IV.

Installation and Usage

Install Dependencies

This script utilizes curl, jq, xxd. These must be installed, e.g. for Debian based machines:

apt-get install -y curl jq xxd

Set Script Variables

The top of the script will contain some parameters to customize the behavior, as shown:

apiToken=**COPY API TOKEN**
outFile=outfile.csv
keySize=32
ivSize=16
testKeys=1

• apiToken - Required. This can be obtained by following the instructions at https://www.qrypt.com/docs/eaas, and copying from there the access token.
• outFile - Output path for the CSV file
• keySize - AES key size in bytes
• iv - IV size in bytes
• testKeys - Flag to test each key by encryption/decryption a string, using OpenSSL

Run the script

The script itself is aes-key.sh, no parameters necessary.

Notes

Tested on Ubuntu 20.04.3 LTS
