Encryption is the process of converting information into a secret code so that the true meaning of the information can be hidden. The science of encrypting and decrypting this information is called cryptography.
This encryption helps to protect the data that you send, receive and store using any device. This can include text messages, emails, and bank information sent through your online account on your smartphone.
How does this encryption work?
You now know that encryption is the process of converting plain text to plain text, such as a text message or e – mail, and we’s called cipher text. This helps protect the confidentiality of digital data stored on computer systems or transmitted over a network such as the Internet.
Decryption is the process of converting the message to its original form when the sender accesses the message.
To decode the message, both the sender and the recipient must use a “secret” encryption key.
An encryption key is a set of numbers used to encrypt and decrypt data. Each key generated with the encryption key algorithm is random.
There are two types of encryption: Symmetric Encryption and Asymmetric Encryption. Let us now see what are the differences between the two.
Symmetric Encryption A single password is used to encrypt and decrypt data.
Asymmetric Encryption uses two keys for encryption and decryption. Data is encrypted by a public key that is shared between users. Data is decoded by an unshared private key.
Types of Encryption
There are several types of encryption, and they are developed based on different needs and security needs. Here are some common examples of encryption.
Data Encryption Standard (DES)
Data Encryption Standard Is considered a low-level encryption standard. The U.S. government established the standard in 1977. Due to the advancement of technology and the reduction in the cost of hardware, it has been decided to discontinue the use of DES to protect sensitive data.
Triple DES stands for DES encryption three times. It works: Encrypts, decodes, and encrypts data – Performing this process three times strengthens the standard of the original DES, but is considered to be as weak as encryption for sensitive data.
The RSA derives its name from the initials of three computer scientists. This uses a robust algorithm for RSA encryption. RSA is popular because of its core length and is therefore widely used for secure data transmission.
Twofish is considered one of the fastest encryption algorithms and can be used by anyone for free. This is mostly used in hardware and software.
Secure Sockets Layer (SSL)
Most websites now use this Secure Sockets Layer (SSL). It’s a way of encrypting data to and from a website. This prevents attackers from accessing that data while migrating.
You can see the tortoise icon in the URL bar and the letter “s” in “https: //” to make sure you are making secure, encrypted transactions over the Internet.
Why is this encryption important?
To protect their secrets. To protect their personal information and bank account information from hackers while surfing the internet.
How Ransomware uses this encryption to commit cyber crimes.
Encryption is designed to protect the data of computer users but can also be used against users.
I told you in my previous malware article how this ransomware works, so let’s see how to get rid of this ransomware.
Install and use antivirus software on all devices, including your mobile phone.
Always keep the security software you use up to date. It helps protect you from cyber attacks.
Keep operating systems and other software up-to-date on your computer or other device.
Backup your important data to an external storage device. If you are a victim of a ransomware attack, you will be able to recover your files after cleaning up this malware.
If you fall victim to this ransomware attack in any way, do not pay the ransom demanded. You can pay a ransom in the hope of recovering your files. But you can’t get them back. There is no guarantee that cybercriminals will return your data to you.
Encryption is essential to protect your sensitive personal information. But it can be used against you in ransomware attacks. It is wise to take precautionary measures to prevent such damage.
