The encryption methods of PPT are: 1. Use the encryption function of PPT to set and encrypt the password, and set a password you remember in the "Encrypted Document" option; 2. Use file encryption software to encrypt PPT. Use encryption software with high security factor and easy operation.
The operating environment of this tutorial: Windows 7 system, Microsoft Office PowerPoint 2010 version, Dell G3 computer.
Basically there are two ways.
1. Use PPT’s built-in encryption function to encrypt password settings.
In order to protect file security and file confidentiality, PPT has added the password setting function from the 2007 version, and added file protection measures. Many company confidential and privacy protection files do not need to be afraid of being maliciously spread. Here is one A very important key point is that the password you set must not be leaked casually, and the file owner must keep it properly.
Use a computer to create a PPT document file and open it normally. We edit our file and save it. Then pay attention to the icon in the upper left corner of the software, which is the office button. Click and the option box will pop up to select the "Prepare" option, and then The pop-up option box selects the "Encrypt Document" option. At this time, we have correctly set the password security. In the password setting box, we'd better set a password that we remember. After confirming and entering the password twice, the password setting is successful
2. Use file encryption software to encrypt the PPT.
When it comes to file encryption software, transparent encryption software will definitely come to mind. Because this type of encryption software has high security and is easy to operate, it is very suitable for office workers and personal use. Because its operation is very simple and convenient, after logging in to the software, you can enjoy the file encryption service normally without any extra operations, and it is very safe. Very high, using high-strength encryption algorithms AES256,512, SM2, SM3 and other National Bureau of Secrecy commercial-grade encryption standard algorithms to meet the confidentiality needs of any type of individual users (including government and military users). I personally recommend using the Redline privacy protection system, which offers free and transparent encryption.
