Why is it important to know how to encrypt a file?
The most valuable currency today is information. That’s why it’s worth knowing how to encrypt a file containing, for example, protected or simply valuable data, so that its leakage does not harm you professionally or privately.
On the one hand, On the one hand, this concerns, for example, classified information regarding the company where you work, on the other hand, the so-called sensitive data, i.e. data revealing racial or ethnic origin, political opinions, religious or philosophical beliefs, health or sexual orientation of third parties.
And this is, of course, an incomplete catalogue. Name and surname, PESEL, address, e-mail, telephone number, ID card – this is enough for someone to take out a high-interest loan on your account or set up a company and steal high-value goods. In turn, careless conduct while working with the above-mentioned sensitive data or classified information may result in a financial penalty or even disciplinary dismissal.
Ignorance is not only no excuse, but – as you can see – it can have severe consequences. However, we have good news – you don’t have to be a programmer to easily ensure data security.
