The main purpose of the digital certificate is to ensure that the application belongs to the entity to which the certificate was issued. The Gretech Corp. digital certificate does not guarantee that a signed application is safe to run, but rather informs the user that the software was digitally signed by Gretech Corp. and verified by a trusted Certificate Authority (CA).
GOM Player (Gretech Online Movie Player) is a 32/64-bit media player for Microsoft Windows, distributed by the Gretech Corporation of South Korea. It is the primary client player for South Korean GOM-TV, and is more popular in South Korea than any other media player. Key strengths inherited from libavcodec include wide ranging ability to play media files, including .flv - without needing to obtain an external codec, and the ability to play some broken media files. Both of those features are present in other projects using libavcodec like VLC and MPlayer, but are absent from some other media software, including Windows Media Player. www.gomlab.com
