SCSP has been using the SHA1 hashing algorithm since version 5.2.4. Any installation made since that version is therefore secure. However, if a manager has been upgraded from an earlier version such as 5.0.x or 5.1.x, it will retain the original certificates. This can be verified by checking the signing algorithm according to HOWTO59835. In that case, the following unsupported procedure can be used to generate new SHA1 compliant certificates.
