The act or process of extending the validity of the data binding asserted by a public key certificate by issuing a new certificate. (The new certificate is typically used to replace the existing certificate, and both certificates typically contain the same Subject DN and SAN information. It is best practice to generate a new key pair and CSR, i.e., re-key, when renewing a certificate, but re-keying is not required by all certificate authorities. Renewal is typically driven by the expiration of the existing certificate but could also be triggered by a suspected private key compromise or other event requiring the existing certificate to be revoked.)

The reason you have to renew is two-fold. Perhaps most importantly, shorter lifespans aid in the proliferation of new standards, algorithms and ciphers. Encryption is advancing every day. Changing out certificates regularly keeps your encryption up to date.
Hackers and other cyber-criminals may take advantage of the expired SSL certificate to tamper with or steal information transmitted between the browser and server, affecting user data security. Certificate expiration will cause unexpected business interruption, leading to operating problems and capital loss.
The longer your certification is active, the more years of verified knowledge and hands-on technical abilities you have. Employers value certifications, and maintaining your certification shows your employer that you're someone they can depend on.
Using an expired certificate makes clients vulnerable to cyber attacks, which can break their trust. Therefore, it is not recommended to use an expired certificate. A website would not last long with an expired one.
SSL is standard technology for securing an internet connection by encrypting data sent between a website and a browser (or between two servers). It prevents hackers from seeing or stealing any information transferred, including personal or financial data.
An expired SSL certificate does not immediately compromise previously encrypted data. However, subsequent data transmissions will be unencrypted and susceptible to interception or tampering.
Expired digital certificates can cause a network outage or downtime incurring adverse effects on an organization's network and functionality. Digital certificates like TLS/SSL certificates play a crucial role in the smooth functioning of your website.
Open your USB token tool and find out the certificate type. If you have a class 3 digital signature then the renewal cost is 2400/- for 2 Years including GST 18%. You can apply for renewal 7 days before your current DSC expires.
