Even if the cloud storage provider’s servers are compromised, the encryption keys stay with the user, adding an extra degree of security and preventing unwanted access.<\/p>

Encryption is also used by file transfer protocols such as Secure File Transfer Protocol (SFTP) and Secure Shell (SSH) to protect files during transport. These protocols encrypt data in transit, ensuring that it cannot be intercepted or interfered with by unauthorized parties. Organizations can confidently communicate sensitive files with clients, partners, or remote team members while protecting data confidentiality by adopting secure file transfer methods.<\/p>

File Encryption Example<\/span><\/h2>

Let’s look at a real-world example to better comprehend file encryption. Consider the following scenario: a company securely communicates private financial records to its auditors. The organization can ensure that only authorized recipients with the decryption key can access the sensitive financial data by encrypting the files with a file encryption tool. This safeguards the reports’ integrity and confidentiality throughout the transmission procedure.<\/p>

Encrypting personal documents, such as passports or social security numbers, on a computer or external storage device is another example. Individuals can protect unauthorized access to their files by encrypting them if their devices are lost, stolen, or compromised. Even if someone has physical access to the files, encryption assures that the data is illegible in the absence of the decryption key.<\/p>

File encryption is also essential for securing sensitive data while it is being transmitted over public Wi-Fi networks. When using public Wi-Fi hotspots, there is a risk of malicious actors intercepting data. Individuals can reduce the risk of illegal access and safeguard the privacy of their data by encrypting files before sending them or by using secure file transfer protocols.<\/p>
