TLS certificate status: Self-signed
Percentage of SSL/TLS servers with certificate status Self-signed certificate. Showing percentages for IRCNet servers only.About this test result: The certificate is self-signed. Since anyone can create such a certificate it is not secure. It allows a Man-in-the-Middle attack.
Note on statistics:
- There is a difference in the gathering of TLS servers between 2017-2019 and 2020-onwards, see SSL/TLS statistics on the data page.
- For certificate validation errors, OpenSSL (s_client) returns a single error only, so only 1 of the errors is picked even though one server cert could have multiple errors.
- However, from 2023 onwards "Expired" is detected even when there are other errors (eg. Unknown CA).
