Check integrity of gnupg-w32cli-1.4.7.exe

[StephenK]

Hi,

I do not have a previous trusted installation of gpg.

I've checked the sha1 hash for the downloaded gnupg-w32cli-1.4.7.exe on the 
main page and it checks:
b806e8789c93dc6d08b129170d6beb9e1a5ae68f

The main page says to double check against announcements in the mailing list 
archives>

I have found this last task impossible. Even searching for the hash it self 
turns up nothing.

How do I confirm the hash? Or specifically which posting contains this info?

Thanks,
Steve
