Web Certificate Trust Chains and State Access Risks Explained Amid Russian Banking Sanctions

The article explains the hierarchical structure of web certificates used for site authentication and traffic encryption, starting from highly protected root certificates stored in air-gapped facilities with Shamir's secret sharing for key protection. Intermediate certificates extend the chain of trust down to leaf certificates deployed on websites. Russian banks have turned to certificates issued under the MinTsifry root after Western and Chinese CAs refused service due to sanctions. The piece highlights that any nation-state with access to a root private key, whether FSB, NSA, or others, could theoretically issue fraudulent certificates for any domain. It notes the limitations of the X.509 standard, which lacks native support for multi-CA signatures, and suggests that separate browsing environments or PGP-style web-of-trust models could mitigate risks. The author concludes that security is already reduced by reliance on any state-controlled CA and that the choice is ultimately which intelligence agency one prefers to trust.
