Quick Crypt is an interesting tool that can be helping us at this very moment to encrypt files individually; This means that if for some reason we are not willing to use the native tool that Microsoft offers us in its versions ranging from Windows 7 onwards (BitLocker), then we could well use the one we are recommending at this moment.
What is the difference between both services? Well, simply in the case of Microsoft's native tool, Bitlocker usually encrypts entire units, which can be a hard drive (internal or external) or a USB pendrive. This is where we could make a notable difference when using Quick Crypt, since this application works only and exclusively with individual files. If you want to know how to encrypt an image that can only be seen by us and using this tool, then you have to continue reading until the end.
Basic and advanced settings in Quick Crypt
Quick Crypt is a tool that you can use completely free, that being the first benefit that we could find in it. On the other hand, the basic functions of this small application are the following:
- The possibility of choosing any type of file from our computer (images, documents, songs or any other).
- Be able to write a password to lock or unlock the file.
These are the basic functions that the developer offers us in Quick Crypt, something that does not involve any type of problems and inconveniences when trying to protect one or more images. Perhaps the first problem is found right there, and that is that if we want to perform this security operation on several files at the same time (and even on a folder containing some documents), unfortunately we will not be able to do it.
What we can do is select one by one to the files that we want to protect, to which we could give the same or different password depending on the level of security and privacy that we want to have in these images hosted on the computer. On the other hand, it is worth mentioning that according to the developer, images that have been encrypted with Quick Crypt They cannot be unlocked on any other different device, This is the great benefit that is also worth mentioning, because if someone has managed to steal these locked images, for our part we should not worry since they cannot be unlocked even when the same tool is used to do so.
What we suggest at the end of the previous paragraph can be seen in the tab Advanced Settings in Quick Crypt; Right there you can see that under the protection algorithm option there is an additional option.
In the image that we have placed at the top you can see that the application has recognized the computer on which the user is working; This means that In this algorithm information from the personal computer will be used so that it becomes part of the encryption code, resulting in what we suggested above, that is, that the files cannot be unlocked on a different computer.
A little further down there is another interesting option, where the user can place the number of days before the file is deleted from the computer where you are. Assuming the same case that the images have been stolen from our computer, if we have set a validity of 5 days, from the day we encrypt them the countdown will begin so that they are automatically deleted.
A few other additional options that are present in Quick Crypt suggest the possibility of creating a zip file, adding a comment to the protected file and the possibility of creating a Profile within this same tool, which will help us use it when let's decide protect other different files under the same modality password or expiration time as we have suggested above.
As you can admire, Quick Crypt is a tool that has very little weight to download and yet a great "weight to use."
