Endpoint Encryption

Hi Expert,

We are working with vendor for exchanging PGP file. We imported their key and encrypted the file and vendor could decrypted it successfully. However, we got below error when trying to decrypt the file which was encrypted by vendor using our public key.

3034:file is marked for your eyes only, ignoring output

3137:eyes only option not specified, discarding output

We are using PGP Command Line 10.2.1 build 54 and the vendor is using PGP desktop 10.1.0 build 860.

I think the eye only is one option during encryption. However, the vendor said they did not choose any option during encryption the file. Could you help to provide me some guide how to resolve this issue?

Thanks,

Norman

Hi Norman,

Perhaps they are using an automated process to encrypt and are not aware of having used that switch.
You should be able to see some output of the content of the file with:
pgp --decrypt <path_to_file>\file.pgp --eyes-only --recipient <recipient_name_or_ID> --passphrase <passphrase_for_recipient_key>

Very likely, you will only see encoded content, but if it works, then they need to send you a new file without the "--eyes-only" switch.

Hi dcats,

Really appreciate your quick response! Do you know how to turn that eyes-only option offer in PGP desktop 10.1.0 build 860?

I tried to google and with no luck.

Thanks in advance!

Hi Norman,

There is no such option in PGP Desktop.  That is a pgp commandline only command, it doesn't have a similar feature in PGP Desktop.

Hi Alex_CST,

But we did got below error when decrypted the file which was encrypted by pgp desktop.

3034:file is marked for your eyes only, ignoring output

3137:eyes only option not specified, discarding output

Do you have any idea how that could happen?

Thanks,

Norman

Are all the files like this from the vendor?  What is their process to encrypt the email?  IMO, they must have pgp commandline somewhere

No mention of any eyes only related commands at all.  Even the command line version of NetShare:

...has no mention of it.

Hi Alex_CST,

Yes, all the files from this vendor got this error. They are using PGP desktop to encrypt the file.

Are you saying they should use PGP command line to encrypt the file, PGP desktop could not be used to encrypt the file?

Thanks,

Norman

To be honest it makes no sense to me.  Have you tried decrypting the file using PGP Desktop?  (You can get a 30-day trial from https://www4.symantec.com/Vrt/offer?a_id=109355)

Hi Alex,

Do you mean the file encrypted by PGP desktop could be only decrypted by PGP desktop?

Thanks,

Norman

No, it should be working.  It's a very strange occurance that its not.  We just need to elminate where the issue is (their end or your end)
