What is the Meaning of Encrypted?

Last Updated on 4 months by Touhid

In this post, we will define what is the meaning of encrypted data in computer system. Encryption is the process of encoding a message using an algorithm to transform message that only authorized users can access the encrypted data. The encrypted message or data is unreadable for unauthorized users. 

What is the Meaning of Encrypted?

What is the meaning of encrypted? Encrypted means plain text data has converted into a form that is unreadable for unauthorized users and only authorized users can access the encrypted data. It protects sensitive data such as financial information by encoding and transforming the information into unreadable cipher text (The encrypted data is called ciphertext).

As a sender if you want to transmit the credit card and bank account numbers to recipient through a network then the data will be converted into cipher text.

For example, of encrypted data:

Plain text: Credit card number: 37828224631

Cipher text:  eCPkUvjGu16ufOhMPTNhV0c07oEOjV+wHR2VIzfqosI=

Now, what is the meaning of decryption? The receiver needs a secret key or password to read the encrypted data back to its original plaintext data. So, the user can read the file, this process is called decryption.

What is the Meaning of End-To-End Encrypted?

What is the Meaning of End-To-End Encrypted? The meaning of end-to-end encrypted (E2EE) is a secure data communication technique where only the sender and receiver can communicate. Here, third party service provider or hackers are preventing from accessing the data while transferring over the network.

In this encrypted process, the data is encrypted on the sender device using algorithm and only the receiver can decrypt the data.

The end-to-end encrypted method protect the data because only the sender and receiver can access the encrypted data. And no one (such as hackers, third parties, governments) can access the encrypted data on the server.

End-to-end encrypted is a method which used most popular messaging service providers such as Facebook, WhatsApp and Zoom. The messages are encrypted before sending and the messages isn’t decrypted until it reaches to the receiver.

Simply put, end-to-end encrypted method ensure that no one can access or read your data while talking or messaging on Facebook, WhatsApp and Zoom.

Types of Encrypted Technique

In above we have defined What is the meaning of encrypted data? Now, we will explain What are the encrypted techniques?

Basically, there are two types of encryption techniques are used for data encoding in use today such as symmetric and asymmetric encrypted technique.

1. Symmetric Encrypted Technique

In symmetric encrypted techniques, both sender and receiver share the same key for message encryption and decryption. This is the simplest types of encrypted techniques that involves just one secret key to encrypt and decrypt the information.

In this encrypted process, sender uses the secret key to encrypt (cipher text) the message before sending it to the receiver. Once receiver receives the message it can decrypted using receiver secret key, returning It to plaintext.

2. Asymmetric Encrypted Technique

Asymmetrical encryption is additionally referred to as public key cryptography, that could be a comparatively new methodology. It increases the safety of the encryption process by utilizing two separates key but mathematically related keys known as a public key and a private key to encrypt and decrypt data.

In this encrypted technique, both sender and receiver have two keys (public key and a private key) of their own.

A message is encrypted with a private key and decrypted with a public key, or the message can be encrypted with a public key and then decrypted with the private key.

Two keys uses in Asymmetric Encrypted Technique

How Does Encryption Work?

When a sender needs to send a message to receiver therefore, before transfer the message was encrypted by a secret key. In that case, sender uses an algorithm to scramble, or encrypt the plain text message. It is then transmitted through network to the receiver, who is able to decode the message with a key.

An algorithm uses the encryption key to encrypt the data into cipher text and the cipher text data back into plaintext using the decryption key. Encryption algorithms are commonly used for online activities such as messages, computer communications, and for file transfers. Typically, they are used to deliver secure data transfers.

There are different types of encrypted algorithms are used to data encrypt and decrypt, which are as follows:

  • Blowfish
  • AES
  • IDEA
  • MD5
  • SHA 1
  • RSA
  • Twofish

The main purpose of encrypted data is kept confidentiality which can help protect data you have send and received. The encrypted technique plays a significant role for data security in cyber world. If plain text or readable data is not encrypted into cipher text then unauthorized users or cyber attackers can access the data.

Benefits of Encrypted Technique

The overall key benefit of encrypted technique is ensuring information or data security. Typically, there are many benefits of using encrypted technique. If you’re considering encrypted technique for your personal or business purpose then you will get the following advantages:

  • Encrypted process is used to protect sensitive data, including personal information.
  • It can help protect data across all devices, even during transfer.
  • It ensures the Integrity of Encrypted Data.
  • Data is protected while a computer is turned off or in sleep mode.
  • It ensures the confidentiality of information from unauthorized revelation and access.
  • It protects information against spoofing and forgeries.


Finally, the main aim of encrypted data is kept privacy that can help you to protect your data. The encrypted technique plays an important role for information security in cyber world. If your plain text data is not encrypted into cipher text then cyber attackers can access your data. We have defined What is the meaning of encrypted data and types of encrypted techniques.
