Hi,
I can confirm that SHA-256 is used as default now, as from 2016 onward the SHA-1 algorithm is deprecated.
You can find more details here:

We have a "Symantec Class 3 SHA256 Code Signing CA" certificate. I can only sign if I set the hash to SHA1. ApplySignature returns a status of "CertificateWrongFormat" if I try SHA256. Am I doing something wrong.
