Webmin, fix to "Error code: sec_error_invalid_key" SSL error


If you are using Webmin as a way of administrating your servers you may be getting the error "Error code: sec_error_invalid_key" when try to log into your servers.


If is because newer browsers no longer accepts certificates with short keys ( 1024 bits or less).

It is easy solved.

Get access to the Webmin interface by using an older version of a browser.,

You can do that by for example running a "Live CD" of Ubuntu, Linux Mint or what ever.

Log into Webmin and goto "Webmin Configuration":

Click on "SSL Encryption"

Goto "Self-Signed Certificate" and create a new certificate with a key of 2048 bits

Click "Create Now" and you done.

Log into webmin administrator again by accept the new certificate in the browser first
