Minimum requirement is MSYS , which is
a small set of the Cygwin tools. Never used gpg-zip myself though.

Oh...I never would have made the connection.  I can see what it
refers to now but when I read it, the algorithm "ALGO" was one I had
never heard of.  Realistically, I wouldn't have caught it even if it was
written as   "--print-md  [files]" 

Thanks again!

Would it be slightly more consistent to use hash instead of algo here?
And/or to note somewhere that the list of available hash algorithms is
the same as what's printed by gpg --version on the Hash: line?

I imagine that with a slight amount of autofoo the same list that's
printed by the --version option could be added to the man page here as
well.

Man page:

   --print-md algo [files]
   --print-mds [files]
  Print message digest of algorithm ALGO for all  given files  or
  stdin.   With  the  second  form  (or  a deprecated "*" as algo)
  digests for all available algorithms are printed.

The question was how to obtain these values with the commands listed in
the coreutils documentation. Could point me to where you obtained these
options since they aren't listed in the gpg docs(man gpg,info gpg,
etc)? 


In any event, thanks.  I'll just create some scripts to alias yours to
what I was trying to use from the coreutils manual.

On my linux system, gpg-zip is a shell script.  I'm guessing that it's
not installed on windows because there isn't an sh compatible shell
there.  Perhaps if you were using cygwin you could get it to work, but
I don't know.

gpg.zip has nothing to do with M$ O/S's.  It's there, but you'll never
use/need it.

It only exists in GnuPG for Unix-like systems (it's a shell script
that calls GPG).

I cannot find any "gpg-zip"-program after installing GnuPG

I'm not sure if I fully understand your question (coreutils has
nothing to do with GnuPG), but GnuPG does have the SHA2 hashes:

gpg --print-md sha256 (thefile)
gpg --print-md sha384 (thefile)
gpg --print-md sha512 (thefile)

The next version of GPG will add:

gpg --print-md sha224 (thefile)

Generally: Decryption works fine even with a revoked key. However, if
there's only the slightest possibility that the private key is not
solely under the owners control, then encrypted files should be
decrypted and then reencrypted with the new key.

One should never ever delete a revoked key - there still might be a
forgotten old backup encrypted to the old key!

The commands sha224sum, sha256sum, sha384sum and sha512sum compute

Coreutils is installed but there isn't any sha224sum, sha256sum,
sha384sum or sha512sum commands available.  Is sha2 utilities part of
some other package?
