PGP decryption in UNIX script

Shell Programming and Scripting
1

Hi,

I have an already running Production script that I need to simulate in QA. The script is trying to decrypt some files using the below command:

pgp --decrypt ${GET_DIR}/*.pgp --home-dir /.pgp

I am getting the following error:

1080:no private key could be found for decryption

Can someone help me with the following:

  • Where do I need to keep the keys and which keys do I need for the decryption?
  • What is the use of --home-dir in the command?

Thanks in advance

If your QA environment is on a different server from the Production environment, then you will need to import the private key to your QA box. The keys are usually in the users home directory in a hidden folder, most likely /~/.pgp

you have to create the keypair in your QA.. or if you want to use the same key pair as your PRD, then export/import it to QA. if you can create a new keypair in qa. you can use

pgp --key-gen

and follow the steps.
a pair of public and private keys will be created.
the below command will give you all the key that are present in your server.

pgp --key-list

to check a single key use

pgp --key-list <USER_ID>

After you create your keys, you need to make them available to others so that
they can send you encrypted information and verify your digital signature.
Export your public key to a file.
To export your key to a file,which you can then freely distribute to others, use
the --key-export option.

pgp --key-export <userID> --output <key_filename>

This exports the public portion of your key.

after exporting the public key.. you need to add the key to your keyring

pgp --key-add <key_filename>

this is the public key that you have exported.

am i clear in explaining?? if any doubts please reply.

Thanks guys.

The problem is that it is working in Prod, so I cannot generate new keys.

I need to move the keys from Prod to QA, but am unsure where I would find them in Prod and where I need to move in QA. Strangely the user that is used to run the scripts does not have a home directory in Prod.

Please advise.
