SSL Checker

An SSL checker scan is a tool that checks the security certificate of a website and provides a report on its validity and trustworthiness. SSL (Secure Sockets Layer) is a standard security protocol that establishes encrypted links between web servers and web browsers. SSL certificates are used to authenticate the identity of a website and to encrypt data transmitted between the website and the user's browser.

An SSL checker scan typically performs the following checks:

1. SSL certificate validity: The scan checks whether the SSL certificate is valid and has not expired. If the certificate is expired, the website is considered insecure.

2. Domain name validation: The scan checks whether the SSL certificate matches the domain name of the website. If there is a mismatch, the website may be a phishing site or an imposter site.

3. Certificate Authority (CA) validation: The scan checks whether the SSL certificate has been issued by a trusted Certificate Authority. If the certificate has been issued by an untrusted or unknown CA, the website may not be trustworthy.

4. Encryption strength: The scan checks whether the SSL certificate provides strong encryption, which is crucial for protecting sensitive data such as passwords, credit card information, and personal details.

5. Mixed content: The scan checks whether the website is serving mixed content (i.e., both HTTP and HTTPS content), which can pose a security risk and make the website vulnerable to attacks.

The results of an SSL checker scan can help website owners identify security issues and improve the trustworthiness of their website. Users can also use SSL checker scans to check whether a website is secure before providing sensitive information or making online transactions.
