TLS negotiated hashing algorithm: SHA-1

Percentage of IRC SSL/TLS servers with hashing algorithm negotiated as SHA-1 hashing algorithm. Showing percentages for charybdis servers only.

About this test result: The SHA-1 hashing algorithm is a 160-bit hash function. It is no longer considered secure since 2010.
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.
