Title
Is it possible to change the hash algorithm used on the web certificate request from SHA1? -
Description
Is it possible to change the hash algorithm used on the web certificate request when creating a new CSR (Certificate Signing Request) - in /admin | Keys | Web Certificate request ? -
Resolution
2.5.915 and below
The Signature algorithm used is SHA1. It is not possible to change the algorithm.
2.5.916 and aboveThe Signature algorithm used is SHA2 - SHA256
NOTE: It is down to the CA configuration which algorithm is used to sign the certificate. Even if the CSR signature is SHA1, the certificate the CA generates can still be signed by SHA256. All versions of 2.5.x support certificates signed with SHA256.
