This means that all the data that passes between the two parties during an active TLS connection is encrypted and cannot be intercepted by third parties. Otherwise known as TLS, transport layer security is a mix of symmetric and asymmetric encryption used to establish an encrypted link between a server and a client and keep messages safe while in transit. Regardless of this, it is widely used by the defense and military sectors. This type of encryption has exhaustion problems, and unless a key hierarchy is maintained or effective key rotation occurs, any time the key is used, it could potentially leak information that can be used to recreate the secret key. Symmetric-key encryption works with a single key that is used to both encrypt and decrypt the message, which is why in order for it to work, the two parties must have the appropriate key. This type of encryption uses a shared key that both the sender and receiver have access to. Basically, the digital ID is sent to the recipient before the encrypted email, so when the actual encrypted email arrives, the recipient can verify that the two keys - the public and the private one - are a match and open the encrypted email or file. With PKI email encryption, the recipient already possesses the sender's private key on file.
The private key is also known as a digital ID, digital signature, or certificate, validated and issued by a Certificate Authority acting as a third party. The sender in this form of encryption which uses S/MIME (Secure/Multipurpose Internet Mail Extensions) technology has both a public and a private key. The operation of maintaining and preserving public encryption keys is referred to as Public Key Infrastructure (PKI).
Public-key (asymmetric) encryption uses two keys, a private and a public one. Symmetric-key encryption is the fastest type and works without any overheads on CPU resources, while TLS is the standard for email encryption. Public-key encryption is the most common type and is the one used in most email encryption solutions. There are three types of email encryption: public-key, symmetric-key encryption, and TLS. The main purpose of encrypting email is to protect sensitive information from being intercepted by third parties. This is the process of transforming readable data (plaintext) into an unreadable format so that only the intended recipient can read and decode it back to its original state.

Let's dive in! What Is Email Encryption?īefore we get into the nitty-gritty of how to open encrypted email messages, it's important to know what email encryption is and how it works. We'll break down what email encryption is and how it works on a practical level on the most popular platforms. If you're here because you're having issues opening an encrypted email or don't know how to view an encrypted email, don't worry, we've got you covered. In fact, email clients don't automatically encrypt messages, so it's no wonder why very few people know how to open an encrypted email or what email encryption means, for that matter. And yet, most of the emails sent on a daily basis are not encrypted. Whether you're a businessperson sending or receiving confidential information or a streamer with personal messages to your fans, keeping your communications safe and secure is crucial.
