Security concerns are becoming more and more urgent as daily online transactions increase. SSL/TLS certificates, which are used to encrypt website connections and shield sensitive data like passwords and credit card details from being captured by hackers, are a crucial component of internet security. You may look for SSL/TLS certificates from Certificate Authorities (CAs) like Let’s Encrypt, Comodo, and others on the website https://crt.sh. It is a helpful tool for anyone interested in keeping track of SSL/TLS certificates and making sure that their website connections are secure.
Ivan Risti, a security researcher who also founded the SSL Labs website, established the crt.sh website in 2017. Although it was initially designed as a tool for SSL/TLS certificate security monitoring, it has since gained popularity as a source for certificate transparency.
SSL/TLS certificates can be publicly logged via the Certificate Transparency system. Google created it in response to security worries regarding fake certificates. Certificate Transparency enables anybody to track the issuance and revocation of SSL/TLS certificates and find any irregularities or potential security risks by openly logging certificates.
https://crt.sh offers a number of services in addition to certificate searches, including certificate tracking, sophisticated search options, certificate details and export, and certificate transparency logs. To monitor your own certificates or look into security issues and vulnerabilities, use these features.
You can keep track of a certificate’s modifications over time, such as when it was renewed or canceled. This can be helpful for both researching prospective security concerns and keeping an eye on the security of your own website. You can look for SSL/TLS certificates using advanced search options by a number of different factors, including the domain name, issuer, expiration date, and more. This makes it simple to locate the particular certificate you’re seeking or to spot any security flaws.
Information about the certificate is provided in the certificate details, including the issuer, the date the certificate was issued, its expiration date, and the domain names for which the certificate is valid. Additionally, you can export certificate details in a number of formats for later analysis. You may keep track of all certificates that Certificate Transparency has publicly logged by using its logs. This can be helpful for finding new CAs, keeping tabs on modifications to the SSL/TLS environment, and keeping an eye on any security risks.
Security analysts, web designers, system administrators, and anybody else who wants to keep an eye on SSL/TLS certificates and guarantee the security of their website connections utilize the command line tool crt.sh. Additionally, it can be used to look into malware campaigns, phishing scams, and other security-related incidents.
