Thank you Stefan, for the quick reply. I had a look at the digest package indeed, showing me the BuiltinDigests enum. What you're saying is that the only way to add another file check hash digest is to alter the code of BuiltinDigests and add a crc32 digest? I would only do that if the community is willing to take over the code, because I do not want to manage my own version of SSHD.
