What to do About Encryption and how does it protect your data ?

 When sending sensitive, confidential, or personal information over the Internet, encryption is an important privacy tool.

Encryption converts plain text into a secret code that hackers, cybercriminals, and other online snoops can't decipher, even if they intercept it before it reaches its intended recipients. When the message reaches its intended recipients, they will use their own key to decipher the information and return it to plain, readable text.

Thus, encryption can help protect the data that you send, receive, and store using a device. Text messages saved on your smartphone, running logs saved on your fitness watch, and banking information sent through your online account are all examples.

What exactly is encryption?

Encryption is a process that scrambles readable text so that only the person with the secret code, or decryption key, can read it. It contributes to the security of sensitive data.

Massive amounts of personal information are managed online and stored in the cloud or on servers that are always connected to the internet. It's nearly impossible to do business without your personal data ending up in a networked computer system, which is why it's critical to understand how to help keep that data private.

This task requires the use of encryption.

What is the process of encryption?

Encryption scrambles plain text, such as a text message or email, into an unreadable format known as "cipher text." This contributes to the confidentiality of digital data stored on computer systems or transmitted over a network such as the Internet.

When the message is read by the intended recipient, the information is converted back to its original form. This is known as decryption.

Both the sender and the recipient must use a "secret" encryption key — a collection of algorithms that scramble and unscramble data back to a readable format — to unlock the message.

What are the two most common types of encryption systems?

A series of numbers used to encrypt and decrypt data is known as an encryption key. Algorithms are used to generate encryption keys. Each key is distinct and random.

Encryption systems are classified into two types: symmetric encryption and asymmetric encryption. Here's how they're distinct.

Symmetric encryption encrypts and decrypts data with a single password.

For encryption and decryption, asymmetric encryption employs two keys. The data is encrypted using a public key that is shared among users. The data is decrypted using a private key that is not shared.

What is the definition of an encryption algorithm?

An encryption algorithm is a set of rules that, when applied to a computer or other technological device such as a smart phone, converts readable data into scrambled cipher text.

These algorithms scramble data into what appears to be randomized code. However, the algorithms purposefully configure this scrambled data so that it can be easily converted back into a readable format by a decryption key.

What are the different kinds of encryption algorithms?

There are various types of encryption, some of which are more powerful than others. Here are some of the most common encryption examples.

Standard for Data Encryption (DES)

Standard for Data Encryption (DES)

The Data Encryption Standard is a low-level encryption standard. The standard was established by the United States government in 1977. Because of technological advances and lower hardware costs, DES is essentially obsolete for protecting sensitive data.

DES three times

Triple DES performs three rounds of DES encryption. It encrypts, decrypts, and encrypts data three times — hence the term "triple." It strengthens the original DES standard, which is now considered too weak for sensitive data by security experts.


RSA is named after the initials of three computer scientists' families. It encrypts with a strong and widely used algorithm. Because of its long key length, RSA is widely used for secure data transmission.

Advanced Encryption Standard (AES) (AES)

As of 2002, the US government standard is Advanced Encryption Standard. AES is used throughout the world.


TwoFish is one of the fastest encryption algorithms and is available for free to anyone. It's found in both hardware and software.

How does encryption protect the Internet?

Most legitimate websites employ "secure sockets layer" (SSL) encryption, which is a method of encrypting data sent to and from a website. This prevents attackers from gaining access to the data while it is in transit.

Do you want to ensure that a website is using this technology? Look for the padlock icon and the "s" in "https://" in the URL bar. If you see these indicators, you'll know you're conducting secure, encrypted online transactions.

It's a good idea to use SSL to access websites when:

You store or send sensitive data over the internet. If you use the internet to do things like file your taxes, make purchases, renew your driver's license, or conduct other personal business, visiting sites that use SSL is a good idea.

It is required for your job. Your workplace may have encryption protocols in place, or it may be subject to encryption-required regulations. Encryption is required in these situations.

Why is encryption important?

What is the significance of encryption? Here are three of them:

#1. There are legitimate concerns about internet privacy.

Encryption protects your online privacy by converting personal information into "for your eyes only" messages that are only intended for the parties who require them — and no one else.

You should ensure that your emails are sent over an encrypted connection or that each message is encrypted.

Most email clients include an encryption option in their Settings menu. If you use a web browser to check your email, make sure SSL encryption is enabled.

#2. Hacking is a lucrative business.

Cybercrime is a global business that is frequently run by multinational corporations.

Many of the large-scale data breaches that you may have heard about in the news show that cybercriminals are frequently out to steal personal information for monetary gain.

#3. It is required by law.

HIPAA requires healthcare providers to implement security features that help protect patients' sensitive health information online.

Under the Family Education Rights and Privacy Act (FERPA), higher education institutions must take similar steps to protect student records.

Retailers must comply with the Fair Credit Practices Act (FCPA) and other consumer-protection laws.

Encryption assists businesses in meeting regulatory requirements and standards. It also aids in the protection of their customers' sensitive data.

Can cybercriminals use encryption to commit crimes?

Although encryption is intended to protect your data, it can also be used against you.

Targeted ransomware is a type of cybercrime that can affect businesses of all sizes, including government agencies. Individual computer users can also be targeted by ransomware.

How do ransomware attacks take place? Attackers use ransomware to encrypt victims' devices, including computers and servers. Attackers frequently demand a ransom before providing a key to decrypt the encrypted data. The goal is to persuade victims to pay in order to regain access to their vital files, data, video, and images.

Ransomware attacks on government agencies can disrupt services, making it difficult to obtain a permit, obtain a marriage license, or pay a tax bill, for example.

Ransomware attacks on large organizations and government agencies typically generate the most attention. However, ransomware attacks can happen to anyone.

How can you safeguard against ransomware?

How can you safeguard against ransomware?

Here are some tips to help protect your devices from ransomware attacks and the risk of your data becoming encrypted and inaccessible.

Install and use reputable security software on all of your devices, including your smartphone. Maintain the most recent version of your security software. It can aid in the protection of your devices against cyberattacks.

Your operating system and other software should be updated. This can be used to patch security flaws.

Avoid automatically opening email attachments. Why? Email is one of the most common ways ransomware is distributed.

Be cautious of any email attachment that instructs you to enable macros in order to view its contents. Macro malware can infect multiple files if macros are enabled.

Make a backup of your data to an external hard drive. If you've been the victim of a ransomware attack, you should be able to recover your files once the malware has been removed.

Think about using cloud services. Because many cloud services keep previous versions of files, you can "roll back" to the unencrypted form, this can help mitigate a ransomware infection.

Don't hand over the ransom. You could pay a ransom in the hope of recovering your files, but you might not get them back. There is no guarantee that the cybercriminal will release your information.

Encryption is critical for protecting sensitive personal information. However, it can be used against you in the case of ransomware attacks. It's wise to take precautions to maximize your benefits while minimizing your risks.

What is the purpose of encryption?

When sending messages, files, or data that are personal, sensitive, or classified, it is critical to encrypt them. If you're sending medical information to your doctor, you don't want hackers intercepting your emails. You don't want criminals to gain access to your financial information after you log into your online banking account. And you don't want scammers stealing the confidential report you're working on for your boss. To keep this information private, all of it must be encrypted.

What is the most secure method of encryption?

There are several effective encryption methods. However, the Advanced Encryption Standard, or AES, is a popular choice among those looking to protect their data and messages. Since 2002, this type of encryption has been the government standard in the United States. AES is used globally.
