Subject: Verification failure on Win32 for some modules due to incorrect binary/text mode hashing
Download (untitled) / with headers
text/plain 3.1k
Some modules fail to verify on Windows because the digests are generated differently than on non-Windows. Example: Cpanel::JSON::XS v4.06 $ cpansign -v Executing gpg --verify --batch --no-tty --keyserver=hkp:// --keyserver-options=auto-key-retrieve C:\msys64\tmp\YNON5WIAq7 gpg: Signature made 08/23/18 09:49:55 Västeuropa, sommartid gpg: using RSA key 2895A881D34270FABFE8F747B4F63339E65D6414 gpg: Good signature from "Reini Urban <>" [unknown] gpg: aka "Reini Urban <>" [unknown] gpg: aka "[jpeg image of size 7578]" [unknown] gpg: WARNING: This key is not certified with a trusted signature! gpg: There is no indication that the signature belongs to the owner.

In this case, the ones in the SIGNATURE file are binary mode hashes and the current ones are text mode hashes. So most likely on the system where the signature was made the code behaves differently then on Windows, i.e. producing binary mode hashes instead of text mode. AFAIK text mode is the correct one for text files since that's how the tests are written. Question, why do we care about text mode? Why not always do binary mode? This code section seems weird to me. Why not use Digest::SHA::addfile on all platforms? Best regards Niklas
