trying to batch/cron pgp

Nick D'Angelo — Thu, 20 Sep 2007 13:02:56 GMT

HPUX11i.

From the command prompt, I can get the following command to work:

pgp -e filename.txt keyuserid

However, it prompts me for Y or N to accept the keyuserid.

I have tried pgp -e +force +batchmode filename.txt keyuserid but it fails on: Encryption error

I should also state that the keyuserid is in my keyring as it works from the prompt, but not in batchmode.

Suggestion?

It might help to know which version of PGP
you are using. It might also help to see a
transcript showing exactly what you did and
what happened when you got it to work
interactively, and an actual script which
fails, and a transcript showing that failure.

I'd guess that you might get a confirmation
request if the userid were ambiguous (but my
version on VMS seems to run with the first
match it finds, so no bets).

HPUX 11i
pgp Version 6.5.8

This is what I execute from the prompt and notice it asks me to confirm Y before proceeding.

gp -e last.log Wachovia

Are you sure you want to use this public key (y/N)?

I have removed the banks name and changed it to bank.com for security reasons.

Sounds as if that's the thing you need to
change.

> [...] Version 6.5.8 [...]

Too new for me, but I'd guess/hope that
there's some mechanism for increasing its
confidence in a particular key. (Or else
of persuading it not to care.)

Steven,

I got around my problem by using expect to generate a response to the question.

Thanks.

based on information found here:

http://www.acm.org/crossroads/xrds6-5/pgptutorial.html

it appears that you need to "certify" the public key
(Keys, sign)

Note the number following the "-ks" is the Key Id from your message:

$ pgp -ks 0x64016085

Yeah. That's the thing.

I have another issue. I set up pgp as root, which is probably a good thing.

However, I need to add permissions to the the batch userid to be able to use the keys and pgp and it is not able to run.

Arrgh.

Is that anything like a problem?

> [...] it is not able to run.

This is not a good description of the
symptom(s).

Not having tried it, I'd assume that one
could make a symbolic link to point one user
to another user's key-ring file. As for
permissions, as I recall, no one cares much
about the public key ring, which is what
you're using here. (It is a _public_ key
ring, after all.)

I have the solution!
A variable must be defined within your pgp script. This variable is the PGPPASS variable. This precludes the need for a y/n interactive encryption. I belive PGPPASS is set you your keyrings passphrase...

To what? No one is asking for a pass-phrase
here (because he's encrypting, not
decrypting).

Oh, yeah. The best way to keep a secret is
to store it in a script. Great "solution",
but not for this problem.
