azonosítótanúsítvány

An azonosítótanúsítvány, often translated as an identification certificate or digital certificate, is a type of electronic document used to verify the identity of an individual, organization, or device. In essence, it acts as a digital passport, confirming that a specific entity is who it claims to be. This verification is typically achieved through cryptographic methods, where a trusted third party, known as a Certificate Authority (CA), issues and vouches for the certificate's authenticity.

The primary function of an azonosítótanúsítvány is to establish trust in digital communications and transactions. When you encounter a website using HTTPS, for instance, the website's azonosítótanúsítvány is used to encrypt the connection between your browser and the server, ensuring that data exchanged remains private and unaltered. Similarly, in electronic signatures, these certificates bind a signature to a specific individual, providing legal validity and non-repudiation.

Azonosítótanúsítványok contain a wealth of information, including the subject's identity details, the CA's digital signature, the certificate's validity period, and the public key associated with the subject. The public key is crucial for encryption and verification processes. The private key, which corresponds to the public key but remains securely held by the subject, is used for signing or decrypting information. The secure management of these keys is paramount to the integrity of the azonosítótanúsítvány system. These certificates are widely used in e-government services, online banking, secure email, and network authentication.
