SSL Validate Check

SSL Validate Check


This type of check is somewhat more complex than the SSL Certificate Check and enables the host and the port to be specified for the validation of a certificate. This also gives you the option of checking the certificate of your mail server or other services, for example. It is also possible to check the domains domains assigned to the certificate. Enter the expected domains, separated by commas, to ensure that the domain is also included in the certificate. Of course, you can also set the remaining validity period min_days_left as a threshold value.

What is an SSL certificate check?

An “SSL Certificate Check” refers to the verification of an SSL (Secure Socket Layer) certificate. SSL certificates are security protocols used to encrypt the transmission of data between a web browser and a web server. They play a critical role in protecting the privacy and security of user data, especially sensitive information such as credit card numbers and personal information.

The SSL Certificate Check is a process that checks the validity and integrity of an SSL certificate. Here are some of the main aspects taken into account during an SSL certificate check:

  1. Validity: It is checked whether the SSL certificate is still valid. SSL certificates have a limited term, typically a year or longer. After expiry, the certificate must be renewed.

  2. Certificate Chain: SSL certificates are organized in a hierarchy called a certificate chain. Verification ensures that each certificate in the chain was issued by a trusted Certificate Authority (CA).

  3. Hostname Verification: The SSL certificate is usually issued for a specific hostname (domain). The SSL Certificate Check ensures that the host name accessed matches the host name specified in the certificate.

  4. Algorithm and key length verification: The encryption algorithms and key lengths used should comply with security standards. Outdated or unsafe algorithms should be avoided.

  5. Integrity of certificate information: It is checked whether the information contained in the certificate is correct and unchanged.

The SSL Certificate Check is important to ensure that communication between a user and a website is secure and that the website is trustworthy. Web browsers automatically perform SSL certificate checks and alert users if problems are detected with a certificate, such as if it has expired or was not issued by a trusted CA. Developers and system administrators also perform manual checks to ensure that all security aspects are met.
