How to Choose the Best Encryption Methods for Databases

Introduction

Encryption is the process of encoding messages or information so that only authorized parties can see it. Encryption has been going on for centuries. For example, in World War II Allied forces were sending out encrypted codes using the unwritten Navajo language, which was impossible for the Japanese to decode.

Today encryption is even more important because we live in an era where privacy and security are constantly under attack from hackers who want access into our personal lives. Thanks to modern technology like AES encryption, there's no reason why hackers should read sensitive information.

How to Encrypt PDF Documents in Java

Proper documentation, intensive contracts, and extensive manuals form the backbone of the business, though, in modern business, much of this is retained digitally using document file formats such as PDF. Because your organization relies on so many of these forms of documentation, it is integral that you can protect the contents within from errors or outside threats. For the proper precautions to be put in place, utilizing encryption and permissions settings will ensure your PDF documents are only used in ways you deem fit, and cannot be accidentally or maliciously altered by other entities. 

Setting these parameters on each document, however, is a daunting and time-consuming task, and, if it is mistakenly forgotten, it can lead to major issues for you and your organization. By using the following two APIs, you can cut this risk as each document will be automatically encrypted with password protection. This password protection includes an owner password to control editor/creator permissions and a user password to control who can view the PDF.

Control Your Privacy: Start Encrypting Your Emails

Sending an email to another person is not as secure as one would think. When you send an email, your email does not travel directly to the computer of the person that expects the email; it needs to hop through a bunch of other mail and proxy servers until it reaches its destination. During all this hopping from server to server, your email content is visible to everyone that knows a little bit about sniffing the network, but more importantly, Internet companies and mail providers can read the content. Think of it as sending a postcard where everyone with access to the postal system (of your postbox) can read the content of the postcard.

A lot of people claim that they have nothing to hide, which I sympathize with, after all, we haven’t done anything wrong, so why should we hide things? However, that is not the point. The point is that you are having a private conversation with another person and sometimes you don’t want anybody else outside that conversation to know what you talked about. And that is your right to have that sort of privacy. The same goes for email and other digital means of communication, where only you and the destination should be reading the content of your email, not a telecom company, not someone sniffing the network, and definitely not your email provider. For the same reason that you do not give up your favorite social media password to anyone, no one should be able to access and read what is yours.
