Java Encryption: a Practical Use Case

Leave a Comment / All, Backend / Fernando Marchuet

When requesting data using online communication, privacy is very important. Sensitive data could be intercepted by an attacker and then misused. To decrease the risk of data interchange, the involved parties use cryptography to encode the data in case an attacker captures it, to guarantee its content safety. For this purpose, two types of cryptography

Dependency Injection and Unit Testing in Golang

Leave a Comment / All, Backend / Fernando Sigüenza

What is dependency injection? Dependency injection is a programming technique that makes a class independent of its dependencies. It achieves that by decoupling the usage of an object from its creation. This helps you to follow SOLID\’s dependency inversion and single responsibility principles, in order to write a good programme. Let’s refresh our memory with
