What is a .SEF file?

The file extension .SEF stands for Encryptafile Signature File. This type of file is a digital signature that is created using the Encryptafile software, specifically after completing the "Sign a File" task. The main purpose of a .SEF file is to confirm the identity of another file, typically an Encryptafile .EFL file, ensuring that the file is from a trusted source and has not been tampered with.

When creating a .SEF file, users have the option to include the digital signature within a digital envelope. This option can be selected within the signature settings of the Encryptafile software. A digital envelope helps to further secure the signature by adding an additional layer of protection.

To open a .SEF file, you will need to use the XenoSystems Encryptafile program. This software is designed to handle the encryption and decryption processes associated with Encryptafile files, including those with the .SEF extension.

Additionally, it's important to note that .SEF files are associated with strong password protection. These passwords are generated by Steganos password software, which is known for creating robust passwords. The Encryptafile software can automatically input these passwords when you are logging into online accounts, which simplifies the process by eliminating the need to remember each password.

Please be aware that starting from the year 2009, newer versions of the Steganos Password Manager and Privacy Suite software have shifted to using the .ESF file extension instead of .SEF for storing these types of files.
