Today, it is quite common seeing people without having their emails encrypted, save the barrier created by digital divide. Most email users get themselves attached to the usage of email; because of the fact that information or data being sent can be accessed at a later date without any room for lose.

Also, because of official purposes, most businesses and organisations find the use of email more presentable and official than phone messages or phone calls.Despite the fact that having an email with you and the person receiving the email having access to the information or data you sent or you receive, it is still risky if the information or data is not protected.

An unencrypted mail is just like the normal letter in usage in the oldies, which paints a picture of risk and bad situation, especially when it has to do with very important information which brings in the need for encryption. Encryption protects data between the sender and recipient.

Basically, the accessible nature of the internet is between sender and the recipient. Email is always at risk for interception or what if email is sent to a wrong person. This will definitely create big problems for both parties.

Even apart from email platforms, social networks like Facebook Messenger, WhatsApp and a few others social networks, are now saturated with end-to-end encryption. Email encryption in this situation covers the unexpected situation.

The Way Email Encryption Goes

Email encryption encodes the content of the message in transit which can only be decoded with a unique cypher. Email encryption is a requirement for everyone who sends sensitive information over the internet.

This will make meaning for some of the largest Banks and corporations to protect their valuable data; it is a great requirement for businesses, real estate, financial services, insurance, legal businesses. If you want to prevent anyone (apart from specified recipient) from reading your email, you should probably consider encrypting your confidential email before sending them to your friends.

In 1991, a program named PGP (Pretty Good Privacy) was created by Philip R. Zimmermann, for decrypting and encrypting files, text, and email files. Today, PGP is considered a hard way or rock-solid way for encrypting email. PGP uses a very smart sense.

What was used in the past was public key cryptography, rather than using a password for encryption and decryption. You can make use of private key and public key.

The major fact is the public key can be given to anyone (audience) to access the information based on encryption while the private key is what you use personally to decrypt the email, which can be installed on your computer without anyone seeing it.

Looking at how encrypting email could be done I will point to OpenPGP.js. This is basically a JavaScript implementation of PGP which enables web developers to add this into their code. You do not have to think about installing any software as more website becomes applications.

This is really cool because it does not matter if you are on Linux, Windows or MacBook. You can use a web browser because this is real as web browser is becoming more and more of Operating System (OS) which is a very good alternative to that.

A common way of encrypting email which is a clear extension of OpenPGP.js is called Mailvelope. Mailvelope is an open PGP encryption as it integrates directly into the webmail user interface and leverage PGP, which is a great gift to the world on encryption.

Mailvelope come preconfigured for major webmail provider such as Gmail, yahoo mail, Mailvelope is a plugin for chrome or Firefox that allows you to do this great encryption in your Gmail, Yahoo mail and Now let’s consider the benefits of email encryption.

1.         Complete Privacy

An unencrypted email has been likened to a post card. You do not know what happens along the way when you send a mail to a targeted recipient or recipients as the case may be. If maybe as a result of circumstances or carelessness on the sender or recipient part, the information being sent got to a third party.

This means the essence of privacy of such information has been defeated. This may be dangerous especially if such information is of great value to the sender and recipient and such information gets to the hands of an unscrupulous person. However, to avoid such unforeseen event, email encryption beforehand will be a very good decision.

2.         Perfect Security

It has been suggested that email users should have two email addresses. One for common use to register in public forums, subscribed to mail list and post on a website and one for private address so that spammers do not attack it.

With these beautiful components of encryption, it shows the idea of encryption is not only geared towards ensuring privacy and confidentiality but only achieving perfect security through it.

3.         Recipient Place Trust in Sender

This is made possible in business relationship where the recipient is very much aware of the encryption. Confidence and trust will be placed on the sender with a strong believe that any interaction is between them only without the knowledge of a third party and secrecy is assured.

4.         Rule out Spams

Most spams tend to possess virus which could be dangerous for your computer system or phone device which is one of the numerous means through which hackers have their way to a user’s computer or phone device.

With email encryption, spams are imaginary because if one is sending emails or attachments, it has in it a digital signature that proves the mail is realisable and real.

5.         Eliminate Possibilities of Risks in Businesses and Organisations

In pursuit of business agendas or operations, businesses, corporations and large organisations make use of emails in furtherance of those pursuits. In this sense, they cannot do without encryption especially where the presence of competing businesses or organisations is real!

There will be a great loss if persons from the society are dealing with a clone created by fraudsters dealing in the name of the business or organisation through an unencrypted email been sent. Encryption rules out such situations.
