If you’ve ever considered the best ways to keep your information secure, you’ve probably found that encryption is necessary. A majority of people naturally don’t know what this means. A smaller percentage of people are even less knowledgeable about its use. While you don’t have to know everything to safeguard your information online, having a basic understanding of important topics such as encryption is still helpful.
Many online stores have encryption strategies in place to protect their customers. However, using a no-cost VPN provides additional security by encrypting your data more and preventing identity theft.
What is data encryption?
It’s a process that transforms unencrypted human-readable data into encrypted information which can only be accessed by people who have the appropriate encryption key. In simple terms, encryption converts the data that is readable into a format that can only be decoded and read by those with the right password. It’s a crucial element in the digital revolution.

What is the process of data encryption? Function?
Cleartext, also known as plaintext, refers to information that doesn’t need to be protected by encryption. Plaintext data must be transmitted through encryption techniques that are mathematical operations performed on raw data. There are many encryption techniques, all with their application and security ratings.
In addition to the algorithms and encryption keys, an encryption key is also required. The plaintext transforms into an encrypted data piece, also called ciphertext. This is done using the specified key and the appropriate encryption technique. The encrypted ciphertext is transmitted via insecure methods of communication instead of the plaintext being sent to the recipient.
If the intended recipient can read the encrypted text, they can use a decryption tool to convert it back into plain text. This key for decryption could or might not be the same as the key used to decrypt the communication; it has to be kept confidential.
Common encryption algorithms
- Triple Des
Triple DES was designed to replace the Data Encryption Standard (DES) algorithm, which hackers could crack fairly easily.
The Advanced Encryption Standard (AES) is a type of cryptographic technique used by the US government and several other organizations and is regarded as a Gold Standard.
- RSA Security
RSA Security is a standard encryption method for data transmission on the internet. RSA public-key encryption technique.
This symmetric cypher divides the message into blocks of 64 bits and secures each block separately.
Data at Rest in contrast to. data that is in transit
Data in motion, also known as “data in motion, ” is information that is actively moving from one location to the next, for example, via the internet or on a private network.
Data at Rest refers to data not moving from one device to the next or between networks like information stored on an external hard drive, laptop or archived/stored differently.
End-to-end as opposed to. VPN encryption
End-to-end encryption (E2EE) for communication applications protects data from being heard, read or altered during the process. End-to-end encryption isn’t accessible on all messaging services. No matter which messaging application you are using, VPNs all have encryption options to ensure privacy and security.
To secure data from end to end, it is encrypted while in transit but not decrypted until it reaches the recipient. The data, however, is encrypted once sent, to be decrypted after it arrives at the VPN server. On the other hand, the most secure VPN for PCs follows a strict no-log policy and does not store any data on its server.
In the end, I would say that both E2EE and VPNs are modern and secure ways to guard the private information of your conversations against getting exposed or hacked. However, VPNs can secure more online traffic and provide advantages.
Different kinds of VPN encryption
Below are a selection of the most popular VPN encryption methods.
- OpenVPN is a highly secured VPN encryption system widely employed nowadays. OpenVPN is a very flexible open-source technology.
- Layer 2 Tunneling Protocol (L2TP) and IPSec are typically used to secure the link between your device and the VPN server.
- SSTP is a Microsoft-owned VPN protocol mostly compatible with Windows operating systems.
- Point-to-Point Tunneling Protocol (PPTP) is a dial-up VPN method.
Does encrypted data have the potential to be stolen?
Hacking is possible using encrypted data. Techniques for encryption, like full disk encryption, are accessible on various endpoint devices. Attackers can use Malware to gain access to an endpoint device and later utilize the device’s keys to unlock information.
Attackers are known to try different keys randomly to crack encryption. It is believed that the size of the key is an immediate correlation with the probability of being successful. As a result, most encryption standards require 256-bit encryption keys. Certain encryption techniques, however, employ weak encryption algorithms that are susceptible to attacks using brute force.
Utilizing phishing and other social engineering methods to fool a trusted user into divulging the key is perhaps the most effective method of hacking encrypted data. The threat of a high person who is privileged changing their mind and using the privileges they have to access data presents the risk of compromising encrypted data.
Users who are inconsiderate and do not adhere to security guidelines are considered insider risks.
Securely encrypt your data and effortlessly using the help of a VPN
A popular way hackers can get identities is to steal data transmitted from a user to an online site. A hacker could be able to intercept crucial details when a user conducts an online purchase. But, with the help of a VPN installed, it is possible to avoid the theft of your credentials online and other vital information.
