Because it uses a unique merging of symmetric & asymmetric keys, data compression, and cryptography keys. The approach permits end-users to create distinct public/private key pairs and share out the distinct public key. But, if a hacker manages to access the receipt account, it’s not enough to stop him/her from accessing the email data.Ĭonsidered the best, PGP or Pretty Good Privacy is a decentralized method that banks upon informal methods for the creation and allocating the public keys. It ensures message delivery is secured and controlled.Īlong with emails, it’s also used in VoIP and instant messages. TLS encryption is a cryptography-based protocol and IETF standard. next, you will see how the use of protocols/layers or the process/algorithm makes a difference.Ĭame after SSL, TLS is an application layer protocol and features TLS handshake and records. The above classification (in the previous section) explained how the use of keys determines the type of encryption. How Does Email Encryption Work? 3 Types of e-mail Encryption A public one for data to be sent (for encrypting), while a different private one by receiver (for decrypting). Two distinct keys are used in this process. Its algorithm is popularly called public key cryptography algorithm too. One can just create and share a discreet key with the aimed receiver o safeguard the end-to-end communication. There is no need to have distinct keys to decrypt & encrypt. It involves using only one discreet key all along the process. The main functional aspect is the algorithm, which is of two kinds. Hence, admins and security engineers must be aware of it. Understanding the modus operandi of a technique promotes its effective usage. It helps an organization safeguard the information’s integrity and meet with certain compliances. Such encoding makes data tough to understand and tougher to modify/distort. People have even faced money stealing from bank accounts because of the unencrypted email exchange.īy encrypting an email, an admin will reduce the chances of the above-mentioned incidences. If a piece of vital information goes into someone's unauthorized hands, there is no end to the misery. As mentioned above, emails are not encrypted inherently, and sharing crucial details in such a manner has a high risk of: They might feature highly sensitive information. This way, data becomes safe to share via internet or in the public domain.Įmails are the first means of communication in today’s digital era. Only those with a decryption key will be able to comprehend what information that respective data is carrying. So, you may consider it as an approach of applying an algorithm that will make data in transit or at rest guarded against any unwanted access. The algorithm, when applied competently, makes the data scrambled during transit. It indicates processing an e-mail message via an algorithm to safeguard your data. Plain e-mails are easy to decode and access.
