PPT (Microsoft PowerPoint) is a software used for making presentations. It provides several encryption methods to protect the security of PPT files. The following are common PPT encryption methods:
Password protection: PPT can be protected by setting a password. Passwords can be applied to permissions to open PPT files or modify files. Only people who know the correct password can access or edit the PPT file.
Content encryption: PPT also supports encryption of document content. This encryption method will encrypt the content in the PPT, including text, images, animations, etc. A password is required to decrypt and view the content.
Digital signature: PPT also supports the use of digital signature mechanisms to ensure file integrity and authentication. Through digital signatures, you can verify whether a file has been tampered with and confirm that the source of the file is trustworthy.
Permission control: PPT provides a permission control function that can limit users' access and editing permissions to files. You can set read-only permissions, allowing only viewing but not modification, or restrict editing permissions to specific users.
These encryption methods can be applied to PPT files individually or simultaneously to improve file security and confidentiality. Which encryption method to use depends on your needs and the level of protection you require for your files. When using the encryption feature, be sure to remember your password and keep it in a safe place to prevent loss or loss of access to your files.
