In today’s digital world, almost everyone has some private or sensitive files that need to be kept confidential under certain circumstances, and that’s where file encryption works. In this post by SwifDoo PDF, we will give you a full introduction to file encryption, from which you will have a better understanding of how to protect your files effectively.

What Is File Encryption

File encryption is a method to protect digital files by converting them to an unreadable format that can only be accessed with a specific key or password. The key can be a combination of letters, numbers, and symbols.

File encryption is used to protect sensitive information from access and editing by hackers, cybercriminals, and other unauthorized users. The encryption and decryption operations are fulfilled by algorithms, which are designed to be mathematically complex, making it difficult for hackers to decipher. Some of the most common encryption algorithms used today are AES (Advanced Encryption Standard), RSA (Rivest-Shamir-Adleman) and, TDEA (Triple Data Encryption Algorithm).

Why File Encryption Matters

File encryption is essential for important information, including financial data, personal information, and intellectual property. It can help ensure the confidentiality and integrity of data, preventing unauthorized access, tampering, and theft.

Encrypted files will have an additional layer of security in a security breach. That will help minimize the impact of a data breach by preventing sensitive information from being leaked.

How to Encrypt a File

File encryption can be done using various tools. Here are some methods:

  • Converting your file to PDF: PDF documents make it easy to protect your sensitive information. You can password-protect your PDF files to limit others from opening, viewing, and editing the content easily using a PDF editor like SwifDoo PDF.
  • Using OS built-in encryption tools: Many operating systems provide built-in encryption tools to help people do file encryption works. For example, BitLocker for Windows and FileVault macOS. You can turn on them in the system setting to encrypt files on your device.
  • Installing third-party encryption software: There are various dedicated encryption software. Some popular examples are VeraCrypt, AxCrypt, and 7-Zip. These applications offer advanced encryption features and can encrypt files of any size effortlessly.
  • Using cloud storage services: Many cloud storage services, including Google Drive and Dropbox, offer built-in encryption features. You can use them to encrypt files both locally and in the cloud.

Using a strong password is essential for file encryption. The minimum length for a secure password is 12 characters, and it should contain a combination of upper and lowercase letters, numbers, and symbols. Besides, it should exclude common words, phrases, or personal information.
