Email encryption has taken the world in a new direction. With the increase in sensitive data security, ‘encryption’ has been a major computing process that has gained immense popularity. With this, various brands have tried to include it in their products such as websites and emails, and more. Since the email encryption market has been in a hustle to offer the best-secured email platforms and other related components, the global email encryption market has seen a major difference. 

This article will focus on an overview of the Email encryption market forecast alongside how the global market has been to date.

Essential Points To Note:

  • Email encryption is an essential part that secures data and attachments at rest or in transmission.
  • There has been an increased need to protect sensitive data across the internet.
  • Email encryption has been widely accepted globally and thus the email encryption market is showing significant growth.
  • The email encryption market forecast reveals that there would be significant development and growth by the year 2027.



What Is Encryption? How Does It Work?

Data encryption is basically a computing process that encodes the cleartext or plaintext data into the ciphertext data and is accessible only to authorized users possessing the correct cryptographic key. In simple terms, encryption is a process in which the authorized users (sender and recipient) of a message are able to lock and unlock a text using some sort of alpha-numeric combination. This means that readable data is first converted into unreadable data by the sender before sending. The recipient after receiving the unreadable data converts it into readable data using a password.

So, what is a key or cryptographic key?

A cryptographic key is essentially a string of characters that are used within an encryption algorithm to alter data. This appears random. Similar to a physical key, it locks the data so that a person with the right key can unlock or decrypt the data.

There are basically three kinds of encryption viz, symmetric encryption, asymmetric encryption, and hashing.

  • Symmetric Encryption

symmetric encryption

It is an algorithm that uses the same key for both encryption and decryption. That said, the computer system or the sender encrypting a message needs to share the secret key with all the authorized parties. This helps the authorized parties to decrypt the message. This kind of encryption algorithm is mostly used to encrypt data in bulk. It is easier and faster to implement than the asymmetric one. The most commonly used symmetric encryption algorithm includes AES (Advanced Encryption Standard with possible keys of 128, 192, or 256 bits), 3-DES, and SNOW. AES is the most used and the best email encryption.

  • Asymmetric Encryption

asymmetric encryption

It is a form of encryption algorithm that uses two different but linked keys, a private key and a public key. As the name states,  a public key is shared publicly and is thus available for anyone to use. On the contrary, the private key is kept secure and is accessible solely to the owner of the key. 

At times, the data is also encrypted two times - once with the private key of the sender and again with the recipient’s public key. This ensures that the data is only available to be decrypted by the intended recipient and validates the sender as well. Some well-known asymmetric encryption algorithm includes RSA (named after its inventors Ron Rivest, Adi Shamir, and Leonard Adleman) and Elliptic curve cryptography.

  • Hashing

It is a data encryption approach that generates a fixed-length unique signature for a data set. That said, the data encrypted using the hashing algorithm cannot be reversed back into its original form or plaintext. Thus, it is mostly used for data verification and is the best email encryption in terms of data validation. This means that hashing is a perfect technique for proving that the data has not been tampered with while transmitting. 

Data encryption is a great means to keep and transfer data in a secured form that does not let other persons view the data it contains. It offers a great form of anonymity and thus reduces specific damages. If you have been asking where is encryption primarily used, now you have an answer.

Why is Data Encryption Necessary?

There are a couple of reasons that establish the fact that data encryption is absolutely necessary. The reasons have been described below. 

1. Data Integrity: Encryption prevents malicious behaviour like on-path attacks. When specific data is transmitted across the web, rigid encryption ensures that the data a recipient receives has not been viewed or tampered with before the recipient has opened it.

2. Privacy: Encryption makes sure that no unauthorized person can read the communications or the data. This keeps the ad networks, hackers, Internet Service Providers (ISPs), and government in some cases from intercepting and reading the sensitive data. This enables the privacy of the users as well.

3. Regulations: The above-mentioned reasons in addition to the security of the data and the users why government regulations and several industries require companies to handle their encrypted user data. The regulatory and compliance standards required for encryption include HIPAA, PCI-DSS, and the GDPR.

4. Security: Encryption is also considered a means to protect from unnecessary data breaches, irrespective of the fact whether the data is at rest or being transmitted. The data on the encrypted devices or hard disks will still be secured if proper encryption had been enabled on the device. 

What Is Email Encryption?

Email encryption is referred to as encrypting or concealing the contents of email messages for protecting potentially sensitive information from being read by unauthorized people. In most cases, email encryption often includes authentication. If you have been looking for email encryption meaning, this is all you need to know.

Emails are a pretty vulnerable thing when they are used in an open WiFi or public WiFi that is completely unsecured. However, in a company that is secure, your emails can also be intercepted if someone else possesses or has acquired your login details. Encryption is thus necessary for these contexts so that the information or the attachments in the emails are safe and goes to the intended person. 

So, what are the things in email that you need to encrypt? Well, here’s all!

  • The connection from your email provider
  • The actual email messages
  • The stored, archived and/or cached email messages.

This was all that has helped the global email encryption market to flourish and keep data safe in the long run. In the upcoming segments, we will be talking about how the global email encryption market has been doing by far and how it is likely to change in the coming years.
