Encryption is the process of encoding information so that only authorized parties can access it, helping to protect the data you send, receive, and store. Encryption takes readable, plaintext data and encodes it into an unreadable format. This encoded information, calledciphertext, prevents unauthorized access. It is a commonly used security measure to protect information and applications, whether stored on computer systems or transferred over the internet. Even if data leaks or a system is breached, the encoded data will be unreadable. When the intended recipient receives the encoded information, it is translated back to its original form - this is called decryption. To view the data, both the sender and the recipient have to use a "secret" encryption key. Typically, encryption techniques include file encryption, drive encryption, email encryption, password encryption, and can be applied to other data transferred over the internet and wireless networks.
The primary purpose of encryption is to protect the confidentiality of stored and transmitted digital data. One of the top advantages is that it can be applied to all or most technology devices. As well as this, encryption is also relatively cheap and easy to implement. Using encryption is exceptionally advantageous to companies as it increases their clients' trust showing they take privacy seriously. It's also essential when employees are working remotely to stop information from falling into the wrong hands. In some companies, encryption technology for data protection is mandatory rather than optional.
