openSSLGOSTSigner

This software is a simple GUI tool which uses openssl command line utility underneath. It designed to sign any type of files with GOST algorithm (GOST cipher) and will be especially useful for russian ISP's and IT companies which in one way or another have to deal with Roskomnadzor's forbidden sites list to reduce the timewaste while typing in commandline each time you need to sign some file.
To use this software you will need to have a ".PEM" file(which exactly used to sign files). If you have your ".PEM" file already - nothing else will be needed. But you can easily make one within this utility. All you need to do this - is a ".PFX"(p12) file.
In the openssl folder you'll find an x86 and x64 installation packets of openssl commandline utility which are HIGHLY recommended to use, 'cause this utility was created and tested exactly with those versions of openssl.
