X-key Lite

File encryption and decryption software. Due to its speed, it is excellent for encrypting large archive backups, or? leaving security copies of backups lying around without protection is not healthy. The program doesn't need to be installed, it can be placed on a USB stick at the same time, for example, with a set of keys.Function: the X-key reads three keys and encrypts the resulting file by combining them (the opposite procedure can also be used, first "Decrypt" the file and if we want to read it, we decrypt it with "Encrypt". Also nice, no?) and allows you to overwrite the original file, or destroy the original file. Destroying the file is done by overwriting it byte by byte and then deleting it, if someone restores it, they will only find unusable data.
