Open Source Code Signing
The certificate confirming the identity of an author working under the Open Source license.
Code Signing certificates enable software developers to digitally sign the original code and recipients to verify data integrity. They eliminate the anonymity of applications published on the Internet by including the author's name. They guarantee that the software has not been modified by unauthorized persons or viruses from the time of its signing by the software developer.
The Open Source Code Signing certificate is meant for software developers and publishers who work under the Open Source licence.

A few words on CERTUM encryption
The encryption procedure allows the protection of information during on-line transmission and connections. The Public Key Infrastructure used by CERTUM is an original solution, created in cooperation with research personnel of the West Pomeranian University of Technology and independent encryption experts. The ID certificates issued by CERTUM allow the use of encryption strength of the recommended key length: 2048/4096.
