How do we put Password protection on files, folders & softwares ?
The free program called TrueCrypt. Encryption does not hide files, it just makes the contents unreadable. Many people encrypt their hard drives but the problem is if you are using Windows to encrypt all the files on your HDD the password is saved on the computer. The use of a third party encryption program is what any person should get. File encryption aka cryptography, is the act of transforming sensitive data through an algorithm to make the file unreadable. Basically data is collected divided into chunks, put through separate algorithms, and put back together. Example: Lets say you want to encrypt “123” easy right. We will first split this string up. (String refers to a instance of text) So… 1 2 3 Put them through an algorithm 1+ 5 = 6 2 + 4 = 6 (3 + 13) / 8 = 2 Put them back together… 662 Now nobody will know what you wrote down unless they have the algorithm. It is much more complicated, but that is the idea. Plain Text: This text is readable… Encrypted Text: cMKRSA2qJUm9/8/
