What are digital certificates, and how do they work?
Digital certificates are electronic documents that use cryptography to verify the identity of individuals, organizations, or devices. They work by using a pair of keys: a public key and a private key. The public key is used to encrypt data, while the private key is used to decrypt it. When a user requests access to a secure website or application, the server sends its digital certificate, which includes its public key and identity information. The user’s browser then verifies the certificate by checking its validity and ensuring that it was issued by a trusted certificate authority.
The verification process involves checking the certificate’s expiration date, ensuring that it has not been revoked, and confirming that the certificate’s issuer is a trusted authority. Once the certificate is verified, the browser uses the public key to establish a secure connection with the server. This secure connection enables encrypted communication between the user’s browser and the server, protecting sensitive data from interception or eavesdropping. Digital certificates are an essential component of secure online communication, enabling trust, security, and efficiency in the digital age.
