turvavaatesid

Turvavaatesid, also known as "trust certificates" or "trust anchors," are digital certificates used to establish trust in a public key infrastructure (PKI). They are typically issued by trusted third parties, such as certificate authorities (CAs), and serve as the root of trust for verifying the authenticity of other certificates in a chain. Turvavaatesid contain the public key of the issuing CA and are self-signed, meaning they are signed with their own private key. This self-signature is what establishes the initial trust relationship.

In the context of secure communications, such as HTTPS, turvavaatesid play a crucial role in verifying the identity of websites and ensuring that the data transmitted between the user's browser and the server is encrypted and secure. When a user visits a website, their browser checks the website's SSL/TLS certificate against the turvavaatesid stored in their trust store. If the certificate is valid and can be traced back to a trusted turvavaatesid, the browser establishes a secure connection.

Turvavaatesid are essential for maintaining the integrity and security of digital communications. They help prevent man-in-the-middle attacks and ensure that users can trust the identities of the entities they are communicating with. However, the management and distribution of turvavaatesid can be complex, involving processes for adding, updating, and revoking trust anchors as needed.
