Secure and Save: 3 Free Ways to Encrypt PDF Files Using WPS Office
Introduction
In today’s digital era, securing sensitive information is crucial. Protecting PDF files from unauthorized access is a standard practice adopted by individuals and organizations worldwide. But how can you safeguard these files without investing in expensive software? Enter WPS Office, a free, user-friendly office suite that not only creates and edits PDFs but also encrypts them with industry-standard AES encryption. In this post, we will discuss three simple ways to encrypt PDF files using WPS Office and ensure that your documents remain secure and confidential.
1. Password Protection
The first way to secure your PDF files using WPS Office is by password protection. This feature allows you to add a password to your PDF file, making it available only to those who know the password. To password-protect your document, follow these steps:
1. Open the PDF file in WPS Office.
2. Click on the “File” tab and select “Info” from the dropdown menu.
3. Click on “Protect Document” and then select “Encrypt with Password.”
4. Type in the desired password twice.
5. Click “OK” to confirm the password.
Your PDF file is now password-protected and can only be accessed by individuals who know the password.
2. Certificate Encryption
Another method of securing PDF files using WPS Office is by certificate encryption. This encryption type requires an authorized digital certificate to decrypt the PDF file, therefore ensuring the recipient’s authenticity. Follow these steps to encrypt your PDF file with certificate encryption:
1. Open the PDF file in WPS Office.
2. Click on the “File” tab and select “Info” from the dropdown menu.
3. Click “Protect Document” and then select “Encrypt with Certificate.”
4. Choose the digital certificate you want to use for encryption and click “OK.”
Your PDF file is now encrypted with a digital certificate, and only authorized parties can access it.
3. Public Key Encryption
The third and final method of securing your PDF files using WPS Office is public key encryption. In this method, two keys – public and private – are used to encrypt and decrypt the PDF file. The public key is shared openly, whereas the private key is available only to the recipient. Follow these steps to encrypt your PDF file with public key encryption:
1. Open the PDF file in WPS Office.
2. Click on the “File” tab and select “Info” from the dropdown menu.
3. Click “Protect Document” and then select “Encrypt with Public Key.”
4. Enter the recipient’s email address and click “Send Public Key.”
5. Wait for the recipient to accept the public key and send back their public key.
6. Select the recipient’s public key and click “OK.”
Your PDF file is now encrypted with public key encryption, ensuring that only the recipient can access it.
