My diploma project in the last year of university. This program is a simplified Certification Authority implemented on Windows Forms. Here you can find emplementation of GOST 34.10-2018 cryptographic digital signature algorithm and GOST 34.11-2018 cryptographic hash function algorithm. To run this program you need .NET Framework and any SQL Server (I used MSSQL. Write your connection string in appsettings.json).
- Create/Verify GOST 34.10-2018 digital signature with key length of 256/512 bit
- Calculate GOST 34.11-2018 hash from any message (256/512 bit length)
- Create self-signed X.509 certificate with Rosstandart Elliptic Curve parameters
- Create signed X.509 certificate with your information
- Create and manage DB with valid and cancelled certificates and the users information
