What is the difference between an RSA certificate and a GOST certificate?

RSA certificates and GOST certificates primarily differ in the cryptographic algorithms used:

• RSA certificate uses the RSA algorithm (Rivest–Shamir–Adleman), based on the factorization of large numbers. It is one of the most common and widely supported algorithms for digital signatures and encryption.

• GOST certificate uses algorithms developed in Russia and standardized as GOST (for example, GOST R 34.10-2012 for digital signatures and GOST R 34.11-2012 for hashing). These algorithms are based on elliptic curves and have their own parameters and features.

Main differences:

• Standards and compatibility: RSA is widely used worldwide, GOST is mainly used in Russia and CIS countries.
• Algorithmic basis: RSA is based on factorization, GOST on elliptic curves.
• Application: GOST certificates are often mandatory for government and some corporate systems in Russia.

Thus, the choice between them depends on security requirements, compatibility, and regulatory standards.
