How to use FSUtil.GetSignature?

[lxp]

Continuing the discussion from Directory Opus 13.9.2 (Beta):

@Jon

Added FSUtil.GetSignature script method. Retrieves information about (and optionally validates) file signatures.

What's the proper way to use the method? I expected this work but received nothing but errors:

DOpus.Output(DOpus.FSUtil().GetSignature('C:\\Program Files\\GPSoftware\\Directory Opus\\dopus.exe').progname);

[Jon]

fs = DOpus.FSUtil();
exe = "C:\\Program Files\\GPSoftware\\Directory Opus\\dopus.exe";
sig = fs.GetSignature(exe, 'vh');
DOpus.Output(sig.valid);

cert = sig.certtimestamp;
DOpus.Output(cert.serial);
DOpus.Output(cert.issuer);
DOpus.Output(cert.subject);
