SSL stands for Secure Socket Layer, which functions to increase website visitors' security from cyber-criminal acts such as theft of electronic data, banking transaction data, and other digital activities so that data stored and sent via the website has a reliable security layer. To keep the site safe, ensure the SSL public and private keys do not expire. The expiration period is usually 12 months, depending on the contract when purchasing SSL. If the validity period expires, extending and reinstalling with a new key is mandatory.
