No secret key under different account

[David Gray-3]

Hello all,

GPG 2.0.12
Windows Server 2003  



I've written a C# application which scans for input files and decrypts using
GPG.
This applications works fine when run under the account (Administrator) that
GPG was installed
under but when run from a different account (SQLService) I get this error.

gpg: encrypted with ELG key, ID 891AB7E7  gpg: decryption failed: No secret
key    
Error Decrypting C:\Program
Files\GNU\GnuPG\work\KLIOLB_20091002_11235900.PGP

I've given full permissions to the SQLService account.

Are there any permissions I need to set within GPG or do I need to specify
anything else on the command line when running under a different account?

The GPG command looks like this

gpg --passphrase-fd 0 --batch --output KLIOLB_20091005_10021900.TMP
--decrypt KLIOLB_20091005_10021900.PGP

Thanks in advance.

Dave

Most likely your keyring is stored under the Administrator account, so  
when run as SQLService, you can't find the keys.

Look at the .gnupg directory in the Administrator account - it needs  
to be available to the SQLService user.  See also the --homedir option  
to GPG, which allows you to specify where the keyrings and config  
files go.

Hi,
Thanks for the info, that makes sense.

That does however mean that I will end up with two sets of keyring
files,
does anyone know a way to share them to certain priv'd users on a
server.

Regards
Dave

Logon to the server as the account you wish to use to encrypt the files.
Import public key as you did prior and sign the key as you did prior.
This worked for me.  I am not in my office, but there are 2 command line
steps that need to be done, on is import and the other I think is sign.
It appears that each user that is to encrypt has to follow this
procedure.

Add the extra keyring(s) with 'keyring <keyring-filename>' or
'secret-keyring <keyring-filename>' line(s) in those users' gpg.conf file

What are peoples thoughts on which is the best option:

a) copy the secring.gpg & pubring.gpg files to the second user account?
b) export and import the keys to the second user account?
c) add a reference to the second account's gpg.conf file?


Also could anyone please give me an example of the syntax for adding keyring
references to gpg.conf?

Thanks
Dave

it depends on what you are trying to accomplish. Any of the above may be the
best option for a given set of requirements. If I wish to use my keys on a new
machine, option a or redirecting gpg.conf to keyrings (& trustdb) on portable
media is probably the route I'd take.

If I wanted to share a central keyring of, for example, customer keys, I
probably go with option c.

no-default-keyring
primary-keyring pubring.gpg
keyring         O:\GnuPG\pubring.gpg
keyring strong.gpg
keyring trusted.gpg
secret-keyring   secring.gpg
secret-keyring   O:\GnuPG\secring.gpg

These should be explained in gpg2.man which should be in the share\gnupg
directory under gpg2's onstallation directory, default on Windows:
C:\Program Files\GNU\GnuPG2\share\gnupg\gpg2.man. It can be read with Notepad

I will stay out of this except to say options A and B are substantively
identical.  Beyond that, this is a system administration question.  I
know nothing of your system, and that means the best thing I can do is
to stay out of it.  :)

Hi,
Thanks for the info & detailed response.  I'm going to go with
option C as you suggest.  Must admit I hadn't realised that .MAN
pages are the docs.

Cheers
Dave
