How do I verify the PGP installations files before installing them?
I've downloaded the trial for PGP desktop for Windows. The first unzip produces
PGPDesktop10.1.1_Windows_Inner.zip and PGPDesktop10.1.1_Windows_Inner.zip.sig
Unzipping the inner zip produces PGPDesktopWin32-10.1.1.exe and PGPDesktopWin64-10.1.1.exe
How do I verify that these PGP installation files are valid before installing them (that is, without already having PGP)? Are there shar1 checksums available or some other way to do this?
