Internxt which I presented here a few weeks ago, is an ultra-secure, open source online backup solution for your photos and files.
A European company based in Spain, it offers services that respect your privacy and your digital security. The Internxt team has just published two completely free online utilities that make it possible to verify that your passwords are sufficiently secure and that a computer file contains a hidden virus. Super simple to use and super practical on a daily basis.
How do you know if a file on your computer contains a hidden virus?

The usefulness of antivirus on our machines is well established. Viruses circulating on the net can steal sensitive information like your credentials or passwords, encrypt and lock your data, perform individual transactions in apps, monitor your computer and even attack other devices on connected networks. A virus has the potential to access almost everything that is enclosed on your hardware.
With Virus Scanner, offered by Internxt, you have at your fingertips a solution that will allow you to check any file before you even open it. Just drag it to the website window and Virus Scanner will immediately tell you if it is ‘clean’ or corrupt. Control any type of suspicious file to detect viruses and malware in seconds.
Are your passwords strong enough to withstand malicious attacks?

Another tool, also free and very practical, offered by Internxt, a checker for your passwords. I talked about it here on Tools Watch, Password Checker allows you to check the strength of your usual passwords with one click.
Do you believe your credentials could not be found? Take the test and you may be surprised. Password Checker provides you with two important pieces of information when you submit a password to it. He first tells you if he has already been compromised by massive password leaks in recent years.
It will also give you a quite interesting estimate. Depending on the complexity of your password, Password Checker will tell you an estimate of how long it takes a hacker to find it. Dizzy.
To complete the service, you will be entitled to the passage to some good tips to choose strong passwords and difficult to break.
And since you are never really sure of anything at 100%, you can also not test your TRUE password online but a copy by changing one or more characters. If Internxt is a company that gives all the guarantees of security, it is far from being the case for many similar services.
