The CEF file extension is used for the CenturionMail Encrypted Package developed by Centurion Technologies. It is a secure encrypted container that can hold multiple documents and files, as well as other non-standard file types. The containerized files are then secured with the AES-256 encryption algorithm. This ensures that the documents are kept secret and secure, even if the recipient has no knowledge of data security. The CEF format also supports digital signature authentication for added security and privacy.
Technical Details
The CEF file format is specifically designed to replace plain text communication formats such as email. It provides a secure means of communication whose contents are encrypted using AES-256 so that only those on the agreed list of recipients can open the message sent. Additionally, a CENTPACKET, CEX, or CEXI format Digital Signature allows users to authenticate who sent the document, ensure its integrity, and protect its confidentiality. This provides an additional layer of security as compared to non-secured digital communications formats.
Similar File Types
CEF is similar in purpose to other secure communication formats such as, PGP, GPG, and SMIME. It is designed to be powerful enough to securely package all kinds of documents, from spreadsheets and images to CAD drawings and videos.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .CEF) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .CEF extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .CEF file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .CEF extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .CEF extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .CEF file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .CEF file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .CEF file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .CEF file) will be extended to the maximum.
It is also good to check
- if the .CEF file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
