SekChek's Naming Conventions for Encrypted Files
SekChek employs various industry-standard encryption algorithms and
techniques to ensure the security of your data. These include Public Key
encryption techniques based on the RSA algorithm, and symmetric encryption
techniques using algorithms such as AES, DES and 3DES as well as proprietary
methods.
The extensions of files encrypted by SekChek reflect the type of encryption they
were created with and can be any of the following:
- .ZIP
- .SCK
- .SDE
.ZIP Files
A ZIP file extension indicates that the file was encrypted using SekChek’s
proprietary encryption techniques.
ZIP files are always created by the SekChek for Windows and Netware Scan
software that runs on the target system. We recommend that these files are
additionally encrypted with SekChek’s Public key. You can do this via the Client
software on your PC after turning on (checking) the ‘Public Key Encryption’
option. The process will create a file with an SCK extension. This is the file
that should be sent to SekChek for processing.
ZIP files are also created by the Client software when you encrypt Scan files
from an AS/400 or UNIX system with the 'Public Key Encryption' option turned off
(unchecked). For additional security, we recommend that you always encrypt
Scan files with the ‘Public Key Encryption’ option turned on (checked). The
process will create a file with an SCK extension. See below for an explanation
of the encryption methods used to create an SCK file.
.SCK Files
A SCK file extension indicates that the Scan file was encrypted with
SekChek’s Public Key using industry-standard encryption algorithms, such as RSA and
3-DES. SCK files can only be decrypted with
SekChek’s non-exportable Private Key, which can only be accessed under
controlled conditions at our secure premises.
SCK files are created by the Client software when the 'Public Key Encryption'
option is enabled (checked). The feature is located on the ‘Options’ page of the
SekChek Client Software. We recommend that you enable this option to ensure all
of your SekChek files are protected by state-of-the-art encryption techniques.
.SDE Files
A SDE file extension indicates that the file was symmetrically encrypted using industry-standard algorithms, such as AES (Rijndael), 3DES and DES. SDE files typically contain SekChek reports.
