ASIN take-home challenge

The goal is to build a small application to show off your skills at production quality level code. You can write it in any language (preference for NodeJs or Java) and it should only take one day (we can trust in you🙂).

The Scenario

A ministry makes available a list of several people who are manually recorded in a xlsx file format. This list must be saved in a relational database in less than 20 minutes so that it can be consulted by a supervisory committee.

Your job is to create a unix-friendly command line application that performs this action.

// None of the tutorals could help me, so I adapted a few codes.
// What I really want is make a full duplex way between NodeJS and Java, using encrypt/decrypt with AES 128 bit

// 1 - you must have to generate the key
openssl enc -aes-128-cbc -k secret -P -md sha1

// key examples: 
// DCDD74627CD60252E35DFBA91A4556AA
// 2CB24CFDB3F2520A5809EB4851168162
