What is Secure Email?


Secure email is different from claiming an encrypted email. you would possibly have heard of message encryption before, but don’t understand exactly what it's or how it functions with regard to email. If so you aren’t alone! Encryption is an incredibly complex topic that we'll only scrape the surface of.

In order to send an attachment securely over email, you’ll get to encrypt it. this is often because you would like security in two areas. the primary is when the email is transmitted to its destination. The second is once an email arrives at its destination. so as to know how encryption aids in both of those aspects of securing your emails and attachments, let’s take a deeper check out what encryption is and the way it works.

What is Encryption?


In the simplest terms, encryption is that the process of taking data during a file attachment or email and scrambling it in order that it's unreadable. so as to read or access the info in an encrypted secure message, you'll need a key. Keys are wont to both encrypt and decrypt data. There are currently two broad categories of message encryption used for the needs of an email server. the primary is public-key encryption which is that the commonest sort of encryption you'll run into. The second is symmetric-key encryption, which is a smaller amount common within the public sphere and more common within the private and governmental sectors.

Public-Key Encryption


Public-key encryption requires the utilization of two sets of keys. One key's publicly available. the opposite key's private and is merely shared between the sender and recipient. Public-key encryption relies on third-party trusted entities that are liable for validating a corporation or individual. So, how does this all work together?

In essence, the sender and recipient both got to know the general public key of the opposite party. The sender will usually send their private key before sending the encrypted message, or in some cases along side it. This private key's often within the sort of a digital signature or digital certificate, which is validated by an external Certificate Authority. An example of a Certificate Authority that you simply may have seen before is that the company DocuSign.

The sender finds the general public key of the recipient, encrypts the message, and sends it along side their digital signature if it hasn’t already been sent. The recipient verifies the authenticity of the sender by comparing the private and public keys. counting on the e-mail client, much of the work is completed on the back-end provided the private key has already been received and therefore the public key's already known.

Symmetric-Key Encryption


Symmetric-key encryption is that the other sort of encryption you would possibly run into. the foremost robust of this sort of encryption is Advanced Encryption Techniques (AES) 256 bit, but there are other sorts of symmetric-key encryption methods available. the method for sending and receiving symmetric-key encrypted emails is comparatively simple. before sending an encrypted email, the sender must share the key with the recipient. This key's the sole thanks to decrypting the e-mail . an equivalent key's wont to encrypt and decrypt the e-mail.

How Secure is Encryption?


Encryption scrambles the contents of a message in order that only the sender and recipient can open the message. But how reliable is encryption? the very fact is, encryption is incredibly powerful. you would possibly be wondering whether the safety of encryption comes right down to computing power alone. While older, outdated methods of encryption are often broken by a brute-force attack given a particular level of resources and time, today’s highest levels of encryption will still be secure within the future. Given current computing power, there's no feasible way that a malicious actor can access the contents of a message encrypted with AES 256 bit or the same encryption standard.

What Are the benefits of Encrypting Emails?


If you've got never encrypted your emails or file attachments, you would possibly be wondering why you ought to bother. the very fact is, most people underestimate the extent of threat facing them and overestimate the safety of their personal or business email. The threat landscape facing both individuals and organizations is rapidly expanding. Cyber threat actors are getting more numerous, while the tools they deploy are getting more advanced and easier to access.

Most people assume that their personal or business email is already secured. the idea is that the transportation of the e-mail from source to destination occurs across a secured channel. Although some email providers like Gmail offer Transport Layer Security (TLS) to guard emails in-transit, this only applies if the destination email provider utilizes TLS also. Additionally, this only protects the e-mail while it's on its thanks to the destination.

So, if you're transmitting sensitive information across email, how are you able to make certain that it won’t be intercepted along the way? On top of this, how are you able to make certain that when it arrives at its destination the intended recipient is that the one opening it? While an increasing number of email providers are offering 2-factor authentication for his or her service, the adoption of 2-factor authentication remains slow.

Encryption offers a way of securing an email while it's in-transit and ensuring that the intended recipient is that the one opening it. during this way, encryption is that the best method of protecting privacy while also offering a way of authenticating the sender or recipient.

Sending a Secure Email Attachment the quality Way


In order to send a secure email attachment, you’ll need to undergo a somewhat complex process. We’ll break down the steps of this process in broad terms, but understand that every specific email provider has different encryption capabilities which will require additional steps.


  • Obtain a digital certificate or signature.
  • Obtain the general public key of the recipient.
  • Encrypt your email with the attachment.
  • Send your email with either your digital signature attached or send your digital signature during a prior email.
  • The recipient must have both your digital signature (private key) and the public key.
  • Using both of those the recipient can authenticate the sender, decrypt the e-mail, and download the attachment.


Sending a Secure Email Attachment With Trustifi


As you’ll notice, sending a secure email attachment through a typical method are often a huge hassle. Once the method has been done a couple of times between a sender and recipient it becomes easier, but the initial process of every party exchanging private and public keys can present complications.

In contrast to the quality method of sending secure email messages and attachments, Trustifi simplifies and streamlines the method for both the sender and recipient. Here’s how it works with Trustifi.


  • Generate an email.
  • Open the Trustifi extension pane and choose the safety options desired.
  • Send the e-mail with the attachment.
  • The recipient opens the e-mail, which redirects to a 2-factor authentication page.
  • 2-factor authentication occurs with either a code texted to the recipient’s phone or code that was already shared between the sender and recipient.
  • The recipient opens the attachment. If needed, the recipient can send an encrypted reply directly from an equivalent page.
