I am developing a Moodle website using SSO. I have configured auth_saml2 moodle plugin and I have tested with test login. I am getting error
Exception: Failure Signing Data: error: 06065064: digital envelope routines: EVP_DecryptFinal_ex: bad decrypt - SHA256
I have tried SHA384, SHA512 algorith but still am getting same error.
Error screenshot.
The error message has been reported on Github in a couple of tickets.

Looks like the certificate might need to be regenerated?
Also a post on Moodle, they switched to OpenID
The certificate needs to be regenerated, from the saml settings click the 'Regenerate certificate' button, or go here:
http://moodle.example/auth/saml2/regenerate.php
and resave the certificate. You will need to re-import the SP metadata again with your IdP.
