This change adds detection of GnuPG extensions in private/experimental S2K specifiers (type 101), and parsing of gnu-dummy (1001) (indicating absent secret key material), and gnu-divert-to-card (2002) (indicating key material stored on a smartcard).
1. Preserve the timestamp.(Will help people to see the real time of files were generated) 2. Correct the permissions for standard. As far as I can tell you, 755 is the standard for binaries and 644 is the standard for non-executable files. 3. Add DESTDIR support as RPM needs to install files to a pseudo folder first which doesn't need to be granted any root access like /usr, and when we build RPMs we never use root to build. PS: I'm packaging pgpdump for Fedora.
