Decrypting Files Automatically

Hi,
I am trying to decrypt a file automatically.I want to use it in a dts
package. I am using following command:
type passphrase | gpg --passphrase-fd 0 --decypt-file "File Name"
in my case it looks like:
type "C:\SampleProjects\GnuPGDotNet\GnuPG\passphrase.txt" | gpg
--passphrase-fd 0 decrypt-files "C:\DocLib\EncryptedFile\Clock1.swf.gpg"
I get one of the following errors:

Reading passphrase from file descriptor 0
usage: gpg [options] [filename]

OR

Reading passphrase from file descriptor 0
gpg: encrypted with ELG-E key, ID ECEB4FC5
gpg: decryption failed: secret key not available

I am using GPG version of 1.4.5 on windowsXP professional and default
dirctory of secring is C:\Documents and Settings\bgadhia\Application
Data\gnupg. And my public key is at C:\DocLib\PublicKey
I am able to encrypt and decrypt using UI tools provieded by GPG and WinPT.
Can anyone please help me.
Thank you in advance.
Bharat Gadhia

Peculiarity with windows dealing with pipes. There should not be a space
between the passphrase and the pipe sign.

BTW, I don't know if the file contains a newline/retrun either, otherwise
that might also cause problems.

Hi Johan,
Thank you for the suggestion. I do not have any space in between passpharse
and pipe sign and my passphrase does not contain any newline/return.
Thank you.
Bharat.

Re: Decrypting Files Automatically [In reply to]

I am using something like this.

gpg --passphrase-fd 0 -o "New File" -d "File Name.gpg" <passphrase.txt

In a batch file you may need to add some or all of the following:
--batch
--yes
--trust-model always
