The SEF file extension is utilized for files that are encrypted using the Steganos privacy application. Steganos .SEF files are stand-alone and contain encryption metadata in addition to the encrypted data.
All of this information is secured with 256-bit Advanced Encryption Standard (AES) encryption, which is one of the most secure methods of encryption available. This file extension can be used to store privately archived, password-protected data or other sensitive information in both home and corporate environments. Other popular file formats with similar functions include .PGP, .CR2, .AAA, as well as files encrypted by commercial software such as AxCrypt or WinZip.
Data Encoding
The SEF file extension is utilized to store both compressed and uncompressed data using the InstraView Data Encoding (IDE) method. IDE is a proprietary method of Steganos which works over a variety of different platforms including Windows, macOS, and Linux operating systems. When creating a SEF file, users have the option to use a secure random password generator for added security.
Platform Availability
The Steganos privacy software enables users to open and view their SEF files on multiple platforms, including iOS, Android, Windows, macOS, and Linux. As long as the correct Steganos privacy application is installed on the target machine, SEF files can be accessed from virtually any device. Additionally, users can share their SEF files between machines using an encrypted transfer protocol such as SSL or SSH.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .SEF) 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 .SEF 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 .SEF 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 .SEF 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 .SEF extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .SEF file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .SEF 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 .SEF file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .SEF file) will be extended to the maximum.
It is also good to check
- if the .SEF file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
